Yeah I think its too early to give up on him or think he's going to be far worse. Plus I'm always of the mindset that the medical/training staffs and the players/coaches have a lot more knowledge about how well these guys can play with injuries or recovering from injuries than we do.
Will give it a few games to see how he's doing.
I think the only reason you might see people clamouring to give him time to get back is that we have a very capable backup at that spot
I agree though that the best way for him to improve is to keep playing and get that trust back in his body
but we see it all the time after big injuries that players are a bit slower to get back their performance levels
