Let's put it this way. Ruff and Nolan would have been just as successful, if not more, with the roster he had.
Often the reputation of guys like Babcock & Bylsma come from them landing the right job at the right time.
Larry Robinson was very so-so as the Kings coach, but looked much better when he was plugged into Lou Lamoriello's system.
BTW - Peter DeBoer to be named coach of the Sharks. So Bylsma looks more certain for Buffalo.
