I think the best chance Braylon has of helping the Jets and Sanchez, would be in the same area of the field that Burress helped last year. The endzone. If he can get quick separation from the CB, then use his length for a quick TD catch, before the defender can recover.
With his hamstring problems, I wouldn't expect to see him running too many go routes. But maybe Braylon and Sanchez can execute a backdoor play to move the chains.
But I really don't know what to expect. I just hope Braylon has something left in the tank, to give the offense some production. Enough to convince the Jets to bring him back for next year.
