Yeah, if you're a crusty old "pure laine Quebequois" that hated PK because he didn't pronounce his name as "Pay Kay", and because he didn't play the white way. Or if you're an english or any other variety of Hab fan that bought into all the "leadership" and "character" nonsense Bergevin was spouting when he made the trade.
Or if you're an "old school hockey guy" who thought the nerds should all put their spreadsheets away, and of course the trade was great, because Weber's got a big slap-shot, is tough to play against, and that PK Subban is a defensive liability that you just can't trust defensively...well, hopefully all of those people will choke on a PK Subban finals appearance or Cup win juxtaposed with Weber's Habs going out in the first round against a team the Sens beat fairly easily the next round.
For those Hab fans that hated the trade and/or loved Subban though, I get not being bothered by him having success. It's a bit of a different situation, because I still think trading him was the right decision and it's worked out for everyone involved, but I quite enjoyed watching Phil lift the Cup last year.
