I think O'Sullivan has pretty much made the big club at this point. There are still games to play I guess but how can you not give him the shot?
I don't think there was ever a doubt that he would make the team, at least not for me. He's got nhl level talent but has had some hard times. He's still that same player, just needs to get his head straight. He'll have every chance to succeed here.
I think O'Sullivan is too smart for his own good sometimes. No matter how much his coaches might get irritated about his defensive lapses at times, he knows damned well that if he keeps scoring he'll keep playing.
