Admittedly, I don't know what Bowman has done to demonstrate that he's learned from his past mistakes, but I am not against second chances in theory.
What I don't get, though, is why you would even rush in to sign him as a GM. Bring him in as an advisor, maybe an assistant GM, and let him work his way back up. Don't just hand him a GM job right after he gets re-instated by the league.
It is not like you're signing up his father to be head coach either. Stan's on-ice track record in Chicago was a mixed bag at best (won some Cups but part of that was Tallon and he's also largely responsible for the team's rapid decline with some really questionable trades and signings).
