Did a little goggling and reading draft profiles on Green2. I like what I read. At Illinois, 3 years at LG in a zone blocking scheme. As a sophomore, honorable mention All Big 10 and All America; as junior, first team All Big 10 and 2nd team All American. His one negative, physically, he has 32" arms. His current playing weight is 315, up from 305.
Drafted in the 3rd round by Pittsburg. If I'm not mistaken, the Steelers are a downhill power blocking team. Green2 was not a fit for their system.
At worst, he should be an adequate stop gap for this year. At best, he may be a diamond in the rough.
