Five lessons from the week that was in Big Ten football:
1. Wisconsin-Ohio State could be the Big Ten's game of the year: In recent years, the Badgers-Buckeyes matchups have been more significant than Ohio State-Michigan or any other conference pairing. This week's showdown at Ohio Stadium could be just as significant. Ohio State is the Big Ten's best team, and Wisconsin might be No. 2 after another dominant rushing performance against Purdue. Both teams ascribe to the power run game but do it in vastly different yet equally entertaining ways. Although the Kenny G show has been terrific for the Buckeyes, top quarterback Braxton Miller should be back for the Big Ten opener. Miller might not be the biggest offensive star on the field, as Wisconsin running back Melvin Gordon has performed as advertised, racking up 624 rush yards and seven touchdowns in the first four games. The game features first-year Wisconsin coach Gary Andersen going up against his former boss, Urban Meyer. One of these teams has held at least a share of the past eight Big Ten titles. The winner takes control of the Leaders Division. Should be a great one.
2. Michigan has real problems: It was tempting to write off Michigan's struggle to beat Akron last week as a hangover from the high-stakes Notre Dame game. But no hangovers the past two weeks. The Wolverines found themselves down two touchdowns in the second half Saturday night at UConn, the same Huskies team that lost at home by 15 to Towson in the opener. Michigan rallied for the 24-21 win, and at least Brady Hoke's team has shown grit at the end of games the past three weeks. But quarterback Devin Gardner committed three more turnovers (two interceptions, one fumble), and he has devolved from potential Heisman candidate to a potential problem spot in just a fortnight. An even thornier issue is the continued inability of the Michigan offensive line to open consistent holes for the running game. If the Wolverines are having trouble running the ball against Akron and UConn, what's going to happen in Big Ten play? There's plenty of time for Hoke & Co. to right the ship, and the upcoming bye week is a welcome sight. But right now, Michigan does not look like the top-15 team we thought it was two weeks ago.
3. The Iowa-Minnesota game has added meaning: We love the pig, but there's a lot more than the Floyd of Rosedale at stake (steak?) this week as Iowa and Minnesota open Big Ten play in Minneapolis. Both teams have shown improvement, especially with their power running games, and enter the matchup with momentum. Iowa exploded for 38 first-half points Saturday against Western Michigan and finished with 59, its highest total since 2002. The Hawkeyes received contributions in all three phases, including two punt return touchdowns from receiver Kevonte Martin-Manley and two pick-sixes from cornerback B.J. Lowery. Iowa's defense has yet to allow a rushing touchdown. After a miserable offensive performance in 2012, Iowa is starting to establish an identity behind its line and a stable of running backs. Minnesota is doing the same, finally showing it can control the line of scrimmage and dominate on the ground. Despite not having its starting quarterback (Philip Nelson) or starting running back (Donnell Kirkwood), Minnesota racked up 353 yards and six rushing touchdowns, including four by backup signal-caller Mitch Leidner, in an impressive win against San Jose State. The Gophers are 4-0 for the second straight season. Both teams have very challenging league schedules, so getting off to a 1-0 start is huge. Big one at TCF Bank Stadium this week.
4. Bo Pelini is still standing, but needs time to regroup: The open week couldn't come at a better time for Nebraska's coach and his team, which ended an emotional week with a 59-20 thumping of FCS South Dakota State. The firestorm from audio-gate should die down, at least a little, as Pelini got through Saturday's game without any further controversy, and received mostly support from Huskers fans. Pelini is hardly out of the woods, though, and must turn his attention to a defense that needs a ton of work before Big Ten play begins Oct. 5 against Illinois. The Huskers surrendered 465 yards to the Jackrabbits, who had a balanced attack (238 yards passing, 227 yards rushing). Pelini called it the defense's worst performance in a season filling up with them. Whether it's youth, talent, scheme or attention to detail, Nebraska's defense must get back on track soon. Although the schedule remains favorable the next month or so, it's hard to see the Huskers repeating as Legends Division champs without some significant upgrades on D.
5. Indiana still hasn't arrived: Indiana entered the year with high hopes for a bowl game this year, and with a warp-speed offense averaging 50 points a game through three weeks, the Hoosiers didn't appear to be deluding themselves. But after an impressive showing last week against Bowling Green, Kevin Wilson's team found itself right back in a familiar spot: unable to defend a good team. Missouri racked up 623 yards -- the most in Memorial Stadium history -- in a 45-28 win in Bloomington on Saturday. The game wasn't even as close as the final score, as Indiana tacked on a touchdown and two-point conversion with 10 seconds to go, and Missouri had three turnovers in the first half to kill promising drives. The Hoosiers' vaunted offense failed to score from the 6:31 mark of the second quarter until there was 11:24 left in the game, and IU punted nine times after punting only five times in the first three games combined. The loss to Navy now hurts even more, as Wilson's team would have to go 4-4 in Big Ten play to become bowl eligible. That seems like an awfully tall order. Penn State comes in next after a bye for both teams, and the Nittany Lions just righted their defense in a 34-0 shutout of Kent State. Penn State has never lost to Indiana and will be favored soundly again on Oct. 5. It might be wait for next year time again in Hoosierland.
