I really think that Grzelcyk has taken a step up so far this year. Its clear that he's still a second year player, but month-over-month I think he's shown consistent improvement in both his own skills (like his stickhandling there to delay/defend the TOR forecheck) as well as his system play (getting to places at the blue line where the puck comes out to keep it in the offensive zone, being available on outlets) have just showed slow steady improvement. McQuaid/Boychuck, while admittedly very different body types, had a similar start where they started slow, got minutes, improved, earned more minutes, and then grew into a regular starter. I think that Grz could be following a similar path of steadily increasing usefulness and value.
