Spring football is over and the offseason is officially here. Let’s all let loose with a collective sigh. Now we have to wait until the night of Thursday, August 29, for the first Big Ten game when UNLV plays at Minnesota. There are lots of barbecues, cannon balls into the swimming pool, croquet, Wiffle Ball and Jarts between now and then.

It’s time to talk the ACC/Big Ten Challenge. The event might be six-plus months away, but the 2013 matchups were released Wednesday afternoon.

The Big Ten put a bow on spring practice last Saturday, but many questions still loom as the schools enter the offseason.

The Big Ten put a wrap on spring football last weekend, with Iowa and Minnesota playing the final spring games in the conference. Now, the long offseason begins. But, honestly, this is when players get better—not from September to December.

The announcement of the new divisions created a buzz across the Big Ten landscape. Leaders and Legends are gone. East and West are in. And a nine-game Big Ten schedule is coming in 2016. Here are 13 observations about the new arrangements.

Iowa had a lot of work to do in spring drills coming off a 4-8 season that was the program’s worst since 2000. The offense, which struggled mightily last season and had just seven touchdown passes, may have turned a corner this spring under second-year coordinator Greg Davis. No doubt, the offense looked good in the spring game. The defense also may have found a playmaker up front.
