In putting together the proving ground posts for both the Leaders Division and Legends Division, I tried to mix up offense/defense and position groups. But in reality, I could have made all 10 selections quarterbacks.
The Big Ten loses three of its top four passers from 2011 -- Russell Wilson, Dan Persa and Kirk Cousins -- and while eight teams return their starting quarterbacks, there are question marks around the league. Quarterback competitions are unsettled at Penn State, Purdue and Wisconsin, and returning starters are hearing some footsteps at places like Indiana and Illinois.
Michigan State has spent years grooming Andrew Maxwell to be its top quarterback, but Maxwell still must show he can get it done on game day. Taylor Martinez is entering his third season as Nebraska's starting quarterback, but he still has to win over Huskers fans with more consistent performances. Everyone assumes Braxton Miller will be a big success in Ohio State's new spread offense, but Miller still has some work ahead.
Wisconsin has only three healthy quarterbacks at its disposal, and while the hope is Danny O'Brien makes a seamless transition from Maryland, like Wilson did from NC State last year, O'Brien has a lot to prove.
Let's put the debate to you fine people. Which Big Ten quarterback has the most to prove in 2012? I've listed five choices, and I'm interested to see who you choose. Be sure to vote.
