Winston’s big first quarter leads Seminoles
By Sharon Katz, ESPN Stats & Info
Below are some storylines from Week 9 of the college football season using ESPN’s new set of analytical storytelling metrics for college football.
There are items that include college QBR, team offense/defense/special teams efficiency ratings (also known as expected points added), and win probability.
For more background on these metrics, read Dean Oliver’s primer on all of them and his explanation of college Total QBR. For complete college Total QBR information, go here.
Oregon rides defense to victory
Oregon outscored UCLA 28-0 in the second half to win its eighth straight game of the season. Its 28 points were split between the offense and defense.
Defensively, Oregon held UCLA to 94 yards in the second half, including 21 pass yards on 10 attempts. The Ducks added 13.6 expected points in the second half, matching their per-game total entering the game, which ranked third in the FBS.
Alabama putting teams away by halftime
In the six games since Alabama allowed 42 points to Texas A&M, its most under Nick Saban, the Tide have five more touchdowns (31) than their opponents have points (26).
In those games, the Tide have outscored their opponents 151-0 in the first half and have had an average win probability of 95 percent at halftime.
Miami comes back on heels of its running game, again
Miami entered the fourth quarter trailing in each of its past two games. The Hurricanes had less than a 25 percent chance of winning in the fourth quarter in each of those games.
Miami came back to win in those games largely because it got its run game going. Against UNC, Dallas Crawford rushed for 69 yards in the fourth quarter, including a 3-yard game-winning touchdown with 16 seconds remaining. Similarly, Duke Johnson ran for 85 yards in the fourth quarter against Wake Forest, including a 1-yard game-winning touchdown with 53 seconds remaining.
In the fourth quarter of those games, the Hurricanes added 6.21 expected points per game on the ground. That means if Miami had had an average rush offense in the fourth quarter (EPA of 0), and all other things remained the same, it would have lost each of its last two games by about three points.
Winston impresses in the first quarter
Jameis Winston threw for 229 yards and three touchdowns in the first quarter against NC State, the most pass yards in the first quarter by a quarterback this season.
Winston had a 99.4 Total QBR after one quarter, and his QBR did not fall below 96.
Winston now has a Total QBR of 89 or higher in each of his past four games. During that time, he has the highest Total QBR in the nation.
South Carolina’s comeback
South Carolina’s win probability fell to below three percent in the middle of the third quarter before the Gamecocks scored 17 straight points to send the game to overtime.
