Yeah, stats wise, he's neck and neck with Winston last year, but as far as Heisman hype goes, it's about the TEAM as well, and signature wins.
Florida State killed every team they played, and in week 7 or 8, they went into Clemson against a top ranked team on a night national televised game and clobbered Clemson. Winston throw for almost 450 yards and 3TDs in that game, and rushed in another TD. That was the turning point.
If JT can go into East Lansing and put up a similar performance and help his team beat MSU, then he has a chance to win the Heisman.
