Indiana football's first depth chart is out. Here's what you need to know.

The document Indiana football fans have been waiting to see all summer is out. Kevin Wilson and the Indiana football staff released their first two-deep of the season -- and there are a few surprises.

Haven't been following Hoosier football over the summer? Here's three things to chew on for the rest of the day.

1. Jordan Howard won the running back job, as expected.

Howard wasn't promised the job when the 1500-yard back transferred in from UAB in January. It was certainly assumed he'd be the favorite to replace Tevin Coleman, but Devine Redding showed promise in limited action last fall. There's no question Howard -- who's in the "best shape of his life" according to Wilson -- will be the feature back. But don't be surprised if Redding sees a healthy amount of carries in Wilson's system, which often features a running back-by-committee approach.

2. Where in the world is Dominique Booth?

J-Shun Harris is out for the year with a knee injury. Camion Patrick will miss at least this season with eligibility issues. If there were a time that Indiana would need the former four-star recruit out of Pike to step up into a starring role, this season would absolutely be it. But Booth is completely absent from the two-deep -- leaving Mitchell Paige and Ricky Jones to compliment Simmie Cobbs on the outside. That means Booth is, at best, the 7th best receiver on Indiana's roster. That is, um, not good.

3. Who will replace Antonio Allen's production?

Take a line from Moneyball: Indiana might not need to replace Allen as a player, but will need to replace his tackling production from the secondary in the aggregate. As of now, it looks like Wilson and Brian Knorr will tap sophomore Tony Fields to fill that role. He'll have a crutch to get up to speed in the role, too: Indiana's linebacking core with Tegray Scales, TJ Simmons, Zack Shaw, and Clyde Newton will be as strong as they've been in recent memory.
