Maybe, but I also think it might just be scheme fit. They might like him fine, but he's not the type of explosive player they really want on their offense.
He might be fine in a different style of offense, or in a different role.
Quinn said when he was hired, in his opening press conference, Quinn was asked to describe the team he wanted to have, and his exact quote was "I would say if I had to say two right now, it'd be explosive and physical. The explosive comes offensively and on the return game from big plays, through the run game, through play action, through the passing gam, ones that can change field position. And those are the explosive plays that you have to keep going and being aggressive to go."
Robinson just doesn't fit the explosive nature of what Quinn said he was looking for since literally his first day. And probably before his first day during the interview process.
If other teams feel like they could use his power and experience, he might have a market.
