Who is talking about cutting him?
I think that Isabella is caught in a bit of a logjam between Fitz and Kirk. If one of those guys go down, he could see more playing time really quickly.
I also think he was really hurt by missing camp with the injury.
Isabella seems like a guy whose learning curve is increased because his impressive speed is less impressive in the NFL vs in college. His lack of size is more accentuated in the NFL than college. That being said, can he overtake Damiere Byrd in that role by the end of the season? Sure, and that is probably all we should expect him to do.
What is interesting is some of the profile redundancies in our receiving corp.
Michael Crabtree 6'1, 215 (boundry WR)
KeeSean Johnson 6'1, 201 (boundry WR)
Trent Sherfield 6'1, 219 (boundry WR)
Damiere Byrd 5'9, 180
Andy Isabella 5'9, 188
Larry Fitzgerald 6'3, 218
Hakeem Butler 6'5, 227
