Zeb wasn't coming back from this and he knew it. The offense is just different with Brock and it's obvious Zeb's skill set doesn't work the way Brock's does. I'm inclined to believe the inverse that you describe and that every party benefits from the departure if it happens now. Team over self can also mean stepping away.You could argue the inverse as well. Do you really want someone to be hanging around the team (possibly draining some resources) who doesn't want to be there?
If I wanted out of something like that (not that I've ever been in that situation), I'd much prefer to cut ties and be don with it, rather than hang around and have to fake enthusiasm.
