He wasn't horrible. He had the lowest completion rate of DBs in his limited time. He did look lost at times, but that's to be expected for a rook changing positions. Keep in mind Tell was a FS at USC, and converted to CB last year. He's built like a tall corner, so filling in for Moore at NB probably wasn't ideal. Can he play NB, IDK. He was never physical in college. He's also not fast (4.6ish). He did score well in agility in the shuttle though.
I really don't know where he'll fit. Not fast enough IMO to play CB1 or CB2. Not sure if he's physical enough to play NB or SS. Probably fine to play split safety in a two high. If he could toughen up, could be good at NB, dime, or SS, but he was never that guy in college. Perhaps a rona year hitting the weights will help.
Brissett was given every opportunity to prove himself to the coaches and GM and he failed. He's a good back up QB and that is where he is at. He had 2 seasons and was given a huge pay check. He is an average starter at best.
Bringing race into this discussion is stupid.
