re: How is Trent Richardson such an awful NFL running back?

Many factora go into why RB or even QB do well or not does well at the next level

* What organization matter a bunch(Coach too)

* OL the RB has in the NFL

* If NFL can't throw on that NFL team that any given RB is on these days. That puts added pressure against the elite NFL schemes/players fro taht RB. Good luck with those odds, and not many RB's succeed with those odds.

* Shoot, I have a theory about just this subject
Sometimes having a great OL in CFB can hurt a RB's development for the next level. A CFB RB who doesn't have that luxury of a great OL all the time. Has to create space and holes at the next level(CFB) weekly. Thus passing those he might of been behind coming out of HS and making his transition not so bad for the next level(NFL). TR might be victim to this situation. It's much easier to run someone over when your running through 5 yards holes. All the while popping out from behind a 300 OL at the last second. The DB is having a bad day then. TR having such a solid OL while at Bama might have hurt his development for the next level. Holes are much tighter in the NFL.
