I'm more worried that, as I've posited before, we lost two years of development under Bylsma. I think Jack desperately needs to be coached. But he has to buy in to what the coach is selling (as does the rest of the team).
Good veteran influence might help too. I'd like to see Pommers stay on Jack's line because Pommers is more of a vet influence than Moulson or Gionta. Maybe still not enough though. This is the tough part about having a completely gutted team with no well respected veteran Sabres on it. There's no one there to say "I won on this team and this is how we do things around here".
