I didn't get the memo, so Vanek is the new whipping boy now that Roy is gone? Ok good, I'll take note.
I think we should keep Vanek because he has elite goal scoring ability, albeit a bit streaky at times. For example, Bobby Ryan has averaged 32.75 goals each season for the past 4 seasons (the only 4 he was a regular player); Nash has averaged 34.6 over the past 5 seasons; Vanek has averaged 32.8 goals over the last 5 seasons.
Therefore, looking at those numbers, is it really worth trading away Vanek + X for Nash or Ryan? I mean Vanek has only 1.8 less goals per season than Nash over the last 5 seasons. Ryan is actually .05 less goals per season for his career than Vanek has had over the last 5 seasons.
Plus, Vanek has been one of our more consistent playoff scorers the last 2 trips. In 2011 he was the only one who could put the puck in the net with 5 goals in 7 games. And I think we all remember the Boychuk Chop in 2010, he was basically carrying the team until that point.
I do not think trading Vanek (other than straight up) is worth it for either of these players.
Plus, I just bought his Jersey last season, and that would be a waste of good money.
