Here's the video for the new Heisman Challenge mode in NCAA Football 13. In the mode you'll get to play as select Heisman Trophy winners from college football history.
As the video shows, you'll be able to put those star players on any team you choose, not just their original team. The video does some heretical things with some of the players by putting them in the jersey of a rival team of their historical team. One thing about the mode I think I can appreciate is that you won't have to go through the inane repetitive drill of getting recruited and playing your way into a starting role through drills on a top flight school in it.
