When NHLers hang up their skates, it's really anyone's guess how long they'll stay retired, especially if they haven't even reached their mid-30's yet. Case in point, a retired NHLer has officially come out of retirement after stepping away from the game just a few months ago.
The Buffalo Sabres thought they were drafting a true power forward when they selected Kassian with the 13th pick of the 2009 draft. Unfortunately, his stay with the franchise would only last 27 games. During his rookie season Kassian was traded to the Vancouver Canucks for Cody Hodgson and Alexander Sulzer.
Kassian would have a solid NHL career as a bottom six forward, with glimpses higher in the lineup, providing grit, and physicality. He would chip in offensively scoring 92 goals and 203 points in 661 games, split between the Sabres, Canucks, Edmonton Oilers and Arizona Coyotes.
