I'll bite even though this is silly talk. He averaged 3.4 yards per carry with Miami and 5.8 yards with Philly. The offensive line and QB had a lot to do with his success and I believe you know that.
With the same offensive line , Kenyan Drake averaged 4.8 yards per carry and was much better in the passing game as well. Jay is a 2 down back in this league and will have success on a good team if he can stick to the basics. He is at his best as a 1 cut runner that hits the gap hard, his problem was that the gaps were much smaller for us last year and he started dancing to much. It drove me nuts when he was dancing behind the line as that just isnt his strength.
I won't knock the kid, this was a beneficial trade for both teams. I think we can run a more productive offense without him just because of his limitations in the passing game. Let's just leave it at that.
