He showed some explosive ability to get in the backfield his first 2 years at Boise:
Freshman (in just 4 games): 3.0 sacks, 4.5 TFL.
Sophomore (11 games): 6.0 sacks, 7.0 TFL.
Obviously the Big 12 is another level and he experienced this season that 235 isn't going to cut it. I think if he can bulk up to 250 he can have a much better 2nd season in the B12.
