they might just know what they have in cadet. they might want ingram to get more carries to work on certain situational snaps, see how robinson responds to extensive work. let's other RB's have a chance to try to make some film.
I wonder if there may be a trade going on like a few said before. We wouldn't get much for Cadet, but if its a player that the team was going to cut anyway and the F.O. had already decided to cut Cadet, then it makes sense.
