The book is closed on spring football in the Big Ten, but what did the chapters reveal? Although no games are played during the spring, which fuels optimism for all 12 teams, the 15 practices provide clues for the upcoming season. The Big Ten saw few major injuries to key players, some good news (the NCAA declaring Michigan State WR DeAnthony Arnett eligible for 2012) and some potentially troubling signs.
It's time to revive the power rankings coming out of the spring. We see separation with the top two teams, while Nos. 3-5 are closely matched. The same holds true for Nos. 7-10.
Here they are ...
1. Michigan State: The Spartans' defense looks like the single best unit in the Big Ten entering the season. Spring practice only enhanced our opinion of Pat Narduzzi's group, which has no shortage of stars. While the passing game needs work, Arnett's presence should help, and the Spartans will rely more on their run game with Le'Veon Bell and an improved offensive line.
2. Michigan: Quarterback Denard Robinson and Fitzgerald Toussaint, who affirmed himself as Michigan's top tailback this spring, form arguably the Big Ten's most dangerous backfield tandem. If Michigan can fill some key pieces on both lines, where there was some shuffling this spring, it will be back in the BCS bowl mix and among the favorites to win the Big Ten crown.
3. Wisconsin: It seems hard to fathom, but Montee Ball appeared to take his game to an even higher gear this spring. The Badgers' star running back will fuel the offense again, although quarterback remains a question mark as Maryland transfer Danny O'Brien arrives this summer. Wisconsin still needs more playmakers to emerge on the defensive line and in the secondary.
4. Nebraska: Tough call on this spot, but the Huskers return their core pieces on offense from a 9-4 team. Footwork-conscious quarterback Taylor Martinez received good reviews this spring, and he should be more comfortable in Year 2 at the helm of Tim Beck's offense. Coach Bo Pelini thinks the defense will be improved and potentially deeper, although the Huskers lose a lot of star power on that side of the ball.
5. Ohio State: There were few dull moments in Ohio State's first spring under Urban Meyer, who began installing an offense unlike any seen in Columbus. After resembling a "clown show" early on, the offense made strides and quarterback Braxton Miller looks like a strong fit for the system. An improved defense, led by linemen John Simon and Johnathan Hankins, should buy the offense some time to get acclimated.
6. Penn State: New coach Bill O'Brien ushered in a historic spring in Happy Valley, and Penn State players for the most part embraced the many changes taking place. The Lions still don't have a quarterback, but they have an excellent running back in Silas Redd and an improved offense line that pleasantly surprised O'Brien this spring. Penn State's defensive front seven, led by linebacker Gerald Hodges and tackle Jordan Hill, might need to carry the team at times.
7. Purdue: Fourth-year coach Danny Hope thinks this is clearly his best team in West Lafayette, and with 18 starters back, it's easy to see why. The Boilermakers are one of the Big Ten's deepest teams at positions like quarterback, defensive tackle, running back and cornerback. Purdue must continue to absorb the new defense installed by Tim Tibesar and fill some key gaps along the offensive line.
8. Iowa: Although Iowa's changes this spring didn't make national headlines like the ones at Penn State and Ohio State, they were very significant. New offensive coordinator Greg Davis began installing a more up-tempo and multifaceted offense that seems to be clicking with senior quarterback James Vandenberg. Jordan Canzeri's ACL injury once again clouds the picture at running back entering the summer, and Iowa needs its young defensive line to grow up in a hurry.
9. Northwestern: The Wildcats showcased one of the league's top wide-receiving corps this spring, and if Kain Colter can improve his passing, the offense should surge. Defense has been Northwestern's bugaboo in recent years, and young players like end Deonte Gibson and cornerback Nick VanHoose stepped forward this spring. It's crucial for the defense to keep making progress if Northwestern wants to maintain its bowl streak.
10. Illinois: There's little doubt Illinois will be a defense-driven team, and the Illini look loaded in the front seven with players like end Michael Buchanan, who turned in a very strong spring, as well as tackle Akeem Spence and linebacker Jonathan Brown. An offense that flatlined late last season began learning a new system this spring and still lacks playmakers at running back and wide receiver. Running back Josh Ferguson's spring-game performance is encouraging.
11. Minnesota: The second spring of the Jerry Kill era brought greater comfort for both players and coaches alike. Quarterback MarQueis Gray made strides in his second spring session as the starter, although the Gophers are still looking for more weapons to surround No. 5. The defensive line should be an improved group after several lifeless seasons. Minnesota still needs to develop depth in the secondary and at wide receiver.
12. Indiana: After playing an insane number of freshmen in 2011, Indiana began to reap the benefits this spring. An influx of junior-college defenders, including linebackers David Cooper and Jacarri Alexander, also should boost a unit that needs all the help it can get. The Hoosiers have some nice building blocks on offense at both quarterback (Tre Roberson) and running back (Stephen Houston, Isaiah Roundtree), but they still have a lot of work to do before the season.
