Poll: Which Big Ten QB needs best spring?

Spring football kicks off in the Big Ten on Saturday as two teams (Northwestern and Indiana) take the field Saturday. Among the many subplots in spring ball is quarterback play.

Although only three teams lose starting quarterbacks from 2011 -- Michigan State, Wisconsin and Northwestern -- there's no shortage of uncertainty under center in the league. There are some full-blown quarterback competitions at places like Penn State, Wisconsin and Purdue. There are new coaches and new systems in place at Penn State, Ohio State, Illinois, Indiana and Iowa. At Michigan State, a longtime backup (Andrew Maxwell) steps into the spotlight. At Purdue, Rob Henry returns from injury.

There are players who have started plenty of games but must reprove themselves, like Illinois' Nathan Scheelhaase, Penn State's Matthew McGloin and, to a lesser extent, Northwestern's Kain Colter. There are others who need to take steps in their development, like Nebraska's Taylor Martinez, Minnesota's MarQueis Gray, Michigan's Denard Robinson and Ohio State's Braxton Miller.

Needless to say, it's a big spring for Big Ten signal callers. Which quarterback needs to have the best spring practice performance? While we'd love to list all of them, we've whittled down the list to five players.

Here's your chance to weigh in.
