My final peace, in regard to Weber:
I'm an analytics guy. I've been interested and invested since the only real debate was Corsi vs Fenwick. I know that Weber's numbers are bad, and I largely know why. Some of it can be explained away in such a way that it's nothing to do with Weber's play, some of it can't. However, I've always said that there are certain intangibles that make Weber a great and valuable defenseman anyway -- his leadership, his physical presence, and of course, the threat of his shot.
I think those things still hold true, and for that reason I think that analytics folks will still point at his advanced stats and call him overrated. From a strict X's and O's perspective, they are probably right. He makes a difference on the ice, but it's not because he's a high IQ, rock solid defense guy. He just has an aura, and Habs fans will grow to love that aura...but don't expect his stats to suddenly fix themselves. His heavy defensive zone deployment will of course play against his possession numbers, but the biggest flaw in his game is his play with the puck, and the consequential trouble that he has getting out of his own end. He *must* be paired with someone who excels in this regard, and they *must* do the heavy lifting in terms of zone exit. It's why he worked so well with two guys that are elite in that regard -- Ryan Suter and Roman Josi. He can't be the guy to carry the puck out. He can't be the guy making your breakout pass. That's the biggest hole in his game. You need a d partner to transition the puck, and you need forwards supporting to gather when he creates separation. If you do that, you'll set him up to succeed and you won't care that he's a poor Corsi player. You'll be irritated that the analytics bloggers blast him while swooning over Mark Giordano, but in the end you'll be happy and love him.
I think that, at the end of the day, PK Subban is a better "hockey player," in terms of driving possession, goals, plays, etc...I think that his greater presence is also an asset, even though it seemingly deterred Montreal management. I do think that Nashville "won" this trade overall, but Montreal fans shouldn't hang their heads, because they're still getting a player that will be beloved, one that we will miss in Nashville for a long time, based on who he was and what he meant to our franchise and our city for so long.
