PFF had Demitris Bell rated highly. So many Bills' fans ate that poo up, and cited PFF as fact and gospel.
Bell was a bastard, which by default means he had a mean streak.
People claimed he was a great pass blocker and a well-rounded run blocker.
Fans and "experts" maintained that the Bills o-line was in no way a problem.
They were wrong.
That said, Dawkins is solid, young, and there are not many people who think that LT is a position of need (outside of OL depth, that is).
