The analytics don?t support the idea that Weber, who turns 31 on Aug. 14, can have the same influence on the game as 27-year-old Subban can.
A source told Sportsnet that Matt Pfeffer, who was hired as an analytics consultant at the beginning of the 2015-16 season, made an impassioned and elaborate presentation to management to dissuade them from following through on this trade.
Ignoring Pfeffer?s advice only served to reinforce the notion that Bergevin was following different criteria in his evaluation of both players, said the source, who also suggested Pfeffer?s vehemence on the matter might have ultimately cost him the job (he was told on Wednesday that his contract won?t be renewed). The Canadiens would not comment on why they aren?t renewing his contract, but they did say that they are looking into other analytics solutions.
Quick, someone make up some fancy stats that say Weber > Subban and Bergevin will probably give you a hockey ops job!
Also, I can't imagine how soul-crushing that would have been for Pfeffer. Not even to just get fired, but to pour your heart into trying to make a (completely reasonable) case for why trading Subban for Weber is absurd and having absolutely nobody listen to you.
