I don't think tonight will change my opinion that this team overall isn't quite there in terms of competing with the very best (Colorado, Tampa, etc.)
The Habs at their very best and with Price in top form are arguably around the 10-12th best team in the league? Debatable of course, but I doubt anyone would say they are top-tier. Yet the Leafs, for whatever reason, let them get back into this series in a big way, and this after the Habs looked ready to pack for the cottage most of game 4.
If the Leafs get past Montreal, the Jets will be a stiff challenge. Toronto pulls any of this 'disappearing act when it's time to finish them' against Winnipeg, they'll be done. If they get to the final four and face a Carolina or Tampa Bay, and somehow shock everyone and get to a clinching game scenario only to take the foot off the pedal for a moment, they'll be done.
What will change my mind is if they (obviously) win tonight, then face the Jets, take over the series and if not finish them off the first chance they get, at least play like they want to.
