After another wild NCAA tournament, a total of 21.9 percent of the 8.15 million brackets entered in Tournament Challenge had the correct winner in Louisville, the top seed overall and the most popular championship pick heading into the tournament. It was the second consecutive year that the most popular pick in Tournament Challenge won it all. Kentucky was picked in 35.1 percent of brackets to win in 2012.

There were two brackets tied atop the leaderboard with 1,660 points. However, the grand prize winner comes from a drawing of the top 1 percent of entries in the game, not just the overall points leaders.

President Obama's bracket

The president's bracket finished in the 74.4 percentile of the contest. He had Louisville reaching the title game, but had the Cardinals losing to Indiana. However, with so many brackets picking Louisville to win it all, his standing took a major drop in the end. Last year, the president finished in the 63.6 percentile.

Notable brackets (national champion, final percentile)


President Obama: Indiana, 74.4
Dick Vitale: Louisville, 96.3
Joe Lunardi: Louisville, 95.5
Mike Greenberg: Louisville, 87.5
Mike Golic: Louisville, 95.5
Michael Wilbon: Georgetown, 12.4
Tony Kornheiser: Indiana, 42.9

A total of 1.4 percent of the 8.15 million Tournament Challenge brackets correctly predicted Louisville and Michigan to meet for the national championship. The Cardinals were the most popular team to reach the championship game (39.7 percent) and to win it all (21.9 percent). Meanwhile, 4.9 percent of brackets picked Michigan to reach the championship game and 2.7 percent to win it all (both the 11th most popular pick among our users).

President Obama's bracket

The President correctly predicted Louisville to reach the national championship game, but he had the Cardinals losing to Indiana in the title game, so he can't earn any more points. However, he is sitting in the 93.2 percentile.

Louisville: 39.7/21.9
Michigan: 4.9/2.7

10:05
PM ET
Just 1,820 out of the 8.15 million brackets in ESPN's Tournament Challenge correctly picked Syracuse and Wichita State to reach the Final Four. Individually, 8.1 percent of brackets had Syracuse in the Final Four, while just 19,157 brackets (0.24 percent) had Wichita State reaching the Final Four.

Also, just 2,776 brackets have Wichita State winning it all (1.5 percent of all brackets have Syracuse winning the title).

Looking ahead to Sunday's games, the four teams playing are all reasonably popular picks to reach the Final Four:
Louisville (52.6 percent), Duke (23.4), Florida (20.4), Michigan (13.3)

However, despite all the popular picks playing Sunday, the number of brackets that will have an entire Final Four correct is going to be very low.

Potential Final Fours

Wichita State/Syracuse/Florida/Louisville: 53
Wichita State/Syracuse/Florida/Duke: 50
Wichita State/Syracuse/Michigan/Louisville: 47
Wichita State/Syracuse/Michigan/Duke: 47

AM ET
Just 19 brackets out of 8.15 million in the Tournament Challenge correctly predicted all of the Elite Eight teams. On Friday 4.2 percent of brackets got all four winners correct (Louisville, Duke, Florida, Michigan), compared to the 990 total from Thursday's games.

Michigan's win over Kansas did knock out 8.3 percent of brackets that picked the Jayhawks to win it all (fourth-most popular pick overall). Meanwhile, 2.7 percent of brackets have the Wolverines going all the way. Michigan's Elite Eight opponent, Florida, ended the Cinderella run of Florida Gulf Coast. The Gators were picked to reach the Elite Eight in 42.0 percent of brackets and the Final Four in 20.4 percent of brackets. A total of 10.7 percent of brackets correctly predicted the Florida-Michigan Elite Eight matchup, including President Obama's.

Louisville's win over Oregon means the most popular pick to win it all (21.9 percent) is still alive. A whopping 52.6 percent of brackets have the Cardinals going to the Final Four. Meanwhile, 41.1 percent correctly predicted Louisville facing Duke in the Elite Eight, the only matchup correctly predicted by more than 3 percent of brackets. It's also the only 1-seed versus 2-seed matchup in the Elite Eight.

Thanks to a number of upsets in the Sweet 16, Duke is now the second-most popular team to win it all of those brackets with a champion still alive (7.9 percent). However, the Blue Devils now face the popular Louisville Cardinals.

Percentage of brackets taking Elite Eight teams to Final Four/Championship Game/Winning it all

Louisville: 52.6/39.7/21.9

While the president's choice of Indiana to win the national title won't happen, he still got five of the Elite Eight teams, including correctly predicting all four winners tonight (Louisville, Duke, Florida, Michigan), and three of his Final Four. He's actually now in the 94.9 percentile.

Tournament Challenge: Upsets take toll

March, 29, 2013
3/29/13
1:12
AM ET
Just 990 total brackets out of 8.15 million in ESPN's Tournament Challenge correctly predicted all four of Thursday's winners: Syracuse, Marquette, Ohio State and Wichita State.

The two upsets in the East Region wiped out the second- and third-most-popular picks to win it all. Indiana was taken in 17.9 percent of the 8.15 million brackets to win it all (including President Obama's). Miami was picked in 10.7 percent of brackets to win the championship. 73.7 percent had Indiana winning in this round, 72.7 percent for Miami -- the second- and third-most-popular picks to reach the Elite Eight. (81.8 percent of brackets have Louisville reaching the Elite Eight). In fact, a whopping 55.4 percent of brackets had the Hoosiers and Hurricanes meeting in the Elite Eight.

Meanwhile, just 2.9 percent of brackets picked both Syracuse and Marquette to reach the Elite Eight (19.1 percent for just Syracuse and 13.3 percent for just Marquette). Interestingly, more brackets had 4-seed Syracuse reaching the Final Four and winning it all (8.1 percent/1.5 percent) than 3-seed Marquette (3.7 percent/0.45 percent).

As for the West Region, just 0.3 percent of brackets predicted the Ohio State-Wichita State matchup in the Elite Eight, but that's because just 0.8 percent of brackets had the Shockers reaching this round in the first place, compared to the 68.1 percent for the Buckeyes. Looking ahead to the regional final, just 19,157 brackets (0.24 percent) have Wichita State in the Final Four, compared to 44.2 percent for Ohio State, the most popular pick from the West at the start of the tournament.

Looking ahead to Friday's action, here are the percentages of brackets picking these potential Elite Eight matchups.

Midwest
Louisville-Duke: 41.1 percent
Louisville-Michigan State: 34.6 percent
Duke-Oregon: 0.8 percent (61,086)
Michigan State-Oregon: 0.6 percent (50,060)

South
Kansas-Florida: 25 percent
Kansas-FGCU: 3,930 total
Michigan-Florida: 10.7 percent
Michigan-FGCU: 2,418 total

President Obama's bracket

The president lost his overall champion when Indiana fell to Syracuse. He still has his other three Final Four teams alive (Ohio State, Kansas, Louisville). He currently ranks in the 66.2 percentile but that number will go down as the tournament continues.

Notable brackets (Final Four teams left/overall champion/game percentile)

President Obama: 3, Indiana, 66.2

Heading into the Sweet 16, none of the 8.15 million brackets got all teams correctly. Four brackets got the closest, picking 15 of 16 teams correctly, while another 760 got 14-of-16. On the other end of the spectrum, 1,046 brackets got none of the Sweet 16 teams.

The biggest surprise Sunday was Florida Gulf Coast becoming the first 15-seed to reach the Sweet 16. Just 0.95 percent of brackets picked the Eagles to reach this round, and a whopping 2,354 brackets have them winning it all. Interestingly, 0.3 percent of brackets predicted the Florida-Florida Gulf Coast matchup in the Sweet 16.

The other double-digit seed to reach the Sweet 16, 13-seed LaSalle, was picked in just 1.3 percent of brackets to reach the Sweet 16. Also, just 966 total brackets correctly predicted the four teams from the West region reaching the Sweet 16 (Ohio State, Arizona, Wichita State, LaSalle).

Interestingly, there were 30,093 brackets (0.4 percent) to pick Florida Gulf Coast and LaSalle to reach the Sweet 16.

Other interesting Sweet 16 combinations
  • 20,353 brackets (0.2 percent) had Florida, Florida Gulf Coast and Miami.
  • 46 percent of brackets had the top four Big Ten teams (Indiana, Ohio State, Michigan State, Michigan). The East bracket was the only one where all four top seeds advanced. 35.5 percent of brackets picked those four teams to advance. It's a far cry from all the other regions, as noted below.

2:01
AM ET
Through the round of 64 in Tournament Challenge, the best showing among our 8.15 million brackets is a 30-2 record, shared by five brackets. Another 107 are a game behind at 29-3. There are no perfect brackets, nor are there any brackets with just one loss. (Note: The leaderboard on the Tournament Challenge game and Bracket Bound app says four are tied for the lead. The fifth bracket is ineligible to win a prize in the game and thus is not included on the leaderboard.)

On the other end of the spectrum, there's one bracket that got just one game right and seven that went 5-27 over the first round.

Notes on biggest upsets:

  • Florida Gulf Coast over Georgetown: This upset busted the final perfect bracket in the field. Not surprising, since only 2.3 percent of brackets picked the upset. And just 2,354 brackets have the Eagles winning it all. Meanwhile, Georgetown was picked in 23.5 percent of brackets to reach the Final Four and 3.5 percent to win it all.
  • La Salle over Kansas State: Just 6.1 percent of brackets had the Explorers winning over Kansas State, including President Obama. At the time, the win dropped the number of perfect brackets from 59 to two. Exactly 1,600 brackets have La Salle winning the national championship.
  • Ole Miss over Wisconsin: Just 20 percent of the brackets picked 12-seed Ole Miss over 5-seed Wisconsin. The Badgers were a popular pick to reach the Sweet 16 (54.7 percent of brackets); they also were picked to reach the Final Four in 9 percent of brackets. President Obama had Wisconsin reaching the Elite Eight.
  • All three upsets: 46,674 brackets picked all of the biggest upsets from the round of 64: Florida Gulf Coast, Harvard and La Salle.
  • No. 12 seeds: 3.7 percent of brackets correctly picked 12-seeds Ole Miss, Cal and Oregon to win in the round of 64. (1.2 percent picked all the 12-seeds to win, including Akron, which was routed by VCU.)
  • Ole Miss vs. La Salle: 2 percent of brackets correctly predicted that 12-seed Ole Miss would meet 13-seed La Salle in the Round of 32.
President Obama's bracket

The president finished the round of 64 with a 20-12 record. He lost two Elite Eight teams in Wisconsin and Georgetown (and a Sweet 16 team in New Mexico yesterday), but did correctly predict La Salle's upset over Kansas State. He sits in the 37th percentile heading into the round of 32.

Just 2.3 percent of brackets in ESPN.com's Tournament Challenge picked No. 15 seed Florida Gulf Coast to beat No. 2 seed Georgetown, by far the biggest upset of this year's NCAA tournament. The Hoyas were picked in 3.5 percent of brackets to win the national championship (eighth-most overall), and 23.5 percent of brackets to reach the Final Four. Conversely, 2,354 brackets picked Florida Gulf Coast to win it all.

The Georgetown loss means there are no more perfect brackets left. There are just seven brackets with one loss and 110 with two losses.

Tournament Challenge: 1 perfect bracket

March, 22, 2013
3/22/13
7:20
PM ET
Through 24 games, there is just one perfect bracket (out of 8.15 million) entered in ESPN.com's Tournament Challenge. The number of perfect brackets had been reduced to two with La Salle's upset win against Kansas State, and the Illinois-Colorado game broke that deadlock at the top.

The one perfect entry is not listed on the leaderboard on ESPN.com or the Bracket Bound app because it is not eligible to win a prize on ESPN.com. That entry has a Final Four of Louisville, Georgetown, Ohio State, and Syracuse, with Louisville beating Georgetown for the title.

President Obama is currently 14-10/15-9 through the first 24 games, landing him in the 37.2th percentile. He lost an Elite Eight team in Wisconsin, but he did pick La Salle's upset of Kansas State. There are 80 brackets to get 23 of 24 correct.

Notes from today's upsets:
-- Just 6.1 percent picked 13-seed La Salle over 14-seed Kansas State. It was the second-biggest upset so far (according to our user picks) in the tournament. About 5.6 percent of brackets correctly picked Harvard over New Mexico State on Thursday.

-- Only 20 percent of brackets had 12-seed Ole Miss beating 5-seed Wisconsin. The Badgers were a popular bracket pick, selected to reach the Sweet 16 in 54.7 percent of brackets and the Final Four in 9 percent of brackets. Plus, President Obama had Wisconsin reaching the Elite Eight. And 3.7 percent of brackets correctly picked the 12-seeds of Ole Miss, Oregon and Cal winning its Round of 64 games.

-- 30.4 percent of brackets picked 9-seed Temple to beat 8-seed NC State. The Owls were the least popular of the 9-seeds to advance.

-- 2.7 percent of brackets picked both Philadelphia schools (La Salle, Temple) to win in this round. And looking ahead to tonight, 1.5 percent of brackets picked the trio of La Salle, Temple and Villanova to win.
