Weber was better defensively and Letang offensively. Who had the better career?
I don't know about this, I would give Weber the edge in both categories especially because his shot is such a weapon in particular on the PP. Letang has superior mobility, speed, and perhaps playmaking ability but is notorious for his ability to go braindead in the offensive zone for no particular reason. Letang can chase down a puck carrier like few I've ever seen, he's got a pretty crazy extra gear he can get in to if he's in pursuit.
Better overall career: Weber
Better playoff career: Letang
I think Weber deserved a Norris more for the year he was nominated and Lidstrom won. I also think that the Letang deserved the Conn Smythe in 2016 waaay more than Crosby. I firmly believe that both Lidstrom and Crosby won those awards in those specific years based on reputation.
