Spring football is in full bloom in the Big Ten, from Lincoln to State College. Many issues must be decided between the conclusion of spring drills and the start of the season. But, most won’t be resolved until fall camp. Until then, here are the 18—yes, 18–biggest Big Ten spring questions.

It’s Senior Night tonight in Bloomington, as Jordan Hulls, Christian Watford and Derek Elston will play their final games in venerable Assembly Hall. So, I’m gonna start daily links there. A big part of this annual rite is speeches by the seniors. And these speeches figure to be emotion-packed, given what these three seniors have witnessed in their time at Indiana.

Snow is still on the ground in parts of the Midwest and the calendar still says “February.” No matter, Northwestern kicked off spring football on Wednesday, the first Big Ten school to take the lid off this beautiful annual rite. Yes, the 2013 season is a day closer. And, that’s a tremendous thing.

And you could make a case for Minnesota’s duo of Tubby Smith/Jerry Kill being ahead of Indiana’s Kevin Wilson/Tom Crean. Kill has had great success in a long tenure as a head coach at places like Northern Illinois and Southern Illinois. Smith won a national championship at Kentucky.

BTN will air a 30-minute special Black History Month presentation called “Football Pioneers” at 9:30 p.m. ET Friday Hosted by Howard Griffith, the show features interviews with former Northwestern head coach Dennis Green,who was just the second African-American head coach in Division I history. We also talk with Sidney Williams, a former Wisconsin quarterback who was Big Ten’s first African-American starting quarterback, and current Purdue head coach Darrell Hazell.
