13. 1. Marcus Mariota, QB, Oregon
2013 Stats: 6 G, 100-165, 60.6%, 1,724 yds., 17 TDs, 0 INT; 41 car., 426 yds., 10.4 avg., 8 TDs
Mariota looks to be the Heisman frontrunner at this point and for good reason. He hasn't thrown an interception through six games, is throwing for almost 300 yards a game, and is averaging over 10 yards a carry. Not to mention he has 25 total touchdowns. Granted, he's not in a conventional offense, throwing mostly short passes to his speedy backs and receivers, but he's having a magical season, plain and simple. He has ideal size, can throw darts and can put touch on passes, and he is probably the fastest quarterback in the nation. His decision-making has been perfect, and though he could use another year in college to hone his passing skills, he is the top prospect in the Pac-12 -- and one of the best prospects in the country. If he enters the draft, he will be a top-5 overall pick.
