Here is the short list for QB's. I used the following stats, metrics, and weightings:

Career QB Rating (using NFL formula) 55%
Completion % (accuracy) 15%
Career Yds (experience) 15%
Conference (competition level) 15%

1. Geno Smith, West Virginia 2.53
2. Matt Barkley, USC 1.93
3. Landry Jones, Oklahoma 1.79
4. EJ Manuel, Florida St 1.71
5. Tyler Wilson, Arkansas 1.44
6. Tyler Bray, Tennessee 1.42
7. Ryan Nassib, Syracuse 1.05
8. Zac Dysart, Miami (OH) 0.97
9. Mike Glennon, NC State 0.88
10. Matt Scott, Arizona 0.79

I used a pretty basic formula and didn't have much time to develop it further. It seems to work well in capturing much of what I want so I say good enough!

The rest of the positions are here:
