At Michigan, early in his career, Braylon was a great talent with a bad tendency to drop balls and not be 'on the same page' as the coaching staff. Lloyd Carr was able to get through to Braylon, get him on board, and he fulfilled the promise of the #1 jersey and became a Wolverine legend.
In Cleveland, after emerging as a star (and great guy in the community btw), he regressed back to the old Braylon. I think this was simply nature taking its course when a great talent, with a 'complicated' personality, gets trapped in a negative atmosphere of incompetant coaches, damaged QBs, bad organization, and a town that turns out to be a bad fit (he's a Michigan guy after all!)
Some would say NYC is a bad place for a 'head case' like Braylon. I think its going to be a tremendous fit. The Jets have transformed into a mature, winning organization under Rex Ryan and Sanchez appears to be a real NFL QB with superstar potential. I think he will thrive in this winning situation after sabotaging himself in the cesspool he just got out of.
The Skins are in the midst of the easist 5 game stretch I can recall ever seeing - StL, Detroit, Tampa, Carolina and KC have all been atrocious minor league teams this year. And the Skins have looked right at home amongst these sh*t teams so far. So as they say, it is what it is. . . .why would you expect anything else from a Snyder/Cerrato team?
