Ingram was playing great before the injury but Robinson has looked very good. If Ingram comes back then it means PT and Robinson will get less snaps which I don't care for either.
No need to rush him back while we are at full health at the position.
Only thing I do know, Don't really care to see Cadet much. He is an average WR that pulls a match up advantage by lining up across from LB's and safeties. If I were a defense I'd treat him like a WR because he can't run between the tackles and doesn't exactly light it up outside the tackles.
