Right. Skylar Green was drafted to produce on special teams right away. HE came in fat and slow, so we cut ties pretty quickly.
Stanback was drafted with the intention of basically redshirting him due to injury for a year, then developing his athleticism. This is basically his rookie year (due to injury) and he's still learning nuances of the pro game. I don't see why people expect more from him at this point. It takes many top flight college WRs 3 years to be any good in the NFL.
Stanback is a long-term project who is progressing as expected. There's no reason to give up on him at this point. If Stanback were cut, he'd be a Dolphin as soon as Ireland cleaned his pants, maybe before.
I'd bet we are keeping 6 WRs. That 6th spot is for Amendola to take if he can. His competition isn't any of the 5 guys ahead of him, it's Jeffferson, Lowber and Polk.
Simple as that.
