We should be seeing some kind of incremental progress which we aren't. I thought we were earlier in the season but he's been pretty flat for a bunch of games now and looking pretty much exactly the same as he did right at the beginning of the season. Maybe it's possible that his body can't keep up with all these games after a season off but in that case he should take some time off.
But anyway who knows, I don't think it's just going to turn on suddenly. It's possible by next year he'll be all-star Hayward, or it's possible what we see now is what he is.
Regardless he is a max paid player so I doubt the Celts are giving up on him any time soon.
