4. ATH Braxton Miller (6-1, 215, 4.56)*
The engine that makes the Ohio State offense go, Miller was one of the top quarterback recruits to come from the high school ranks two years ago and he hasn't disappointed. An explosive, dynamic dual-threat signal caller, he has shown the ability to win with his rocket arm or athleticism, already totaling 5,184 total yards in his first two seasons in Columbus. Miller set career-bests last season as a sophomore, leading the team with 1,271 rushing yards, 2,039 passing yards and 28 total touchdowns (15 passing/13 rushing). He has explosive footwork and a fluid body type to get himself out of trouble with his legs and vision, making defenders miss with the acceleration and long-speed to finish runs. As a passer, Miller is still a work-in-progress. He has all the arm strength necessary to be productive at the college and NFL levels, generating torque through his hips to make snap throws, but his accuracy and touch have been shaky. Miller, who is still looking for his first 250-yard passing game in college, boosted his completion percentage as a sophomore, but in 12 games last season, he finished north of 60% just three times. He has the bad habit of prematurely vacating the pocket before he needs to, but he can adjust his throwing platform on the move with a quick set-up and delivery. Right now, Miller is the type of athlete that will garner early round consideration in the draft, but he still has a lot of work to do before scouts are convinced he has the passing consistency to start at quarterback in the NFL.
