Hasn't been much discussion on this, and probably for good reason since nobody seems to have seperated themselves from the pack. It was probably Andrew Luck's trophy to lose until Stanford's collapse against Oregon at home, but he even still might be the front runner.
As a Virginia Tech student, I have to wonder why the hell David Wilson hasn't even been listed as a top 10 candidate for the Heisman, even up to this point. He leads the nation in rushing, averages 6.5 yards per carry, and has made tons of ridiculously athletic plays this year. He has carried Virginia Tech's offense this year when Logan Thomas struggled, and is a huge reason why Virginia Tech is ranked #8 right now.
I'm not trying to be a homer and say that he should win, but it's ridiculous that he's not even being considered, especially with this weak crop of candidates this year.
