I agree - don't keep a player due to draft position, and I don't think Gluten will. Sounds like Amari worked ******* his body and conditioning in the off season. That still needs to translate to production on the field. And like you, I haven't been hearing much about him. Doubs on the other hand seems to be tearing it up.
IMO, this is where GMs earn their pay. I've said I don't put a lot of stock in stories coming out of TC, and not much more from PS games. No player wants to get hurt in a practice or meaningless game. So the coaches and GM have to look through that, and the small details, to decide who will fit on the 53. Just not an easy job.
