I agree with Don. Trading Subban for Weber. What need did it address? The Habs were so flush with 30 goal scorers that the screaming need on the team was to tweak the top defensive pairing, giving up almost 4 years of age to do so? Weber may have an edge on defensive play, but Subban  is more of a playmaker. He'll take a bad risk now and then, but he also delivers. And while Weber's plus/minus was better at +20, he also accumulated most of that during the 13--1-1 start, where I recall him being +17. The rest of the way, a little more than a wash.
