Alright, I found how many sacks each team allowed to get a great look at the %s. Here you go:
1. Green-Ellis 65.3%
2. Dixon 58.9%
3. Foster 53.9%
4. McFadden 53.1%
5. Boyd 51.2%
6. Moreno 50.2%
7. Tebow 44.3%
8. Little 42.5%
9. Tate 39%
10. Grant 38.7%
11. Hester 38.2%
12. Jackson-Garrison 31.9%
Now, this still isn't the most accurate because Little missed 3 games and Grant missed 2. I calculated the amount of carries in those games, and did an adjusted percentage to find the % of carries a player got in the games he played. Changes a little, but not much.
