I remember reading an article a couple weeks back where Carrick stated he needed to focus on getting better in his own zone and building an "NHL body" so that he could have a chance at a call-up. He's not small, but still pretty slight for being 6'2" (185 lbs). With the exception of Liles, every single Canes Defenseman is over 200lbs and all of them can skate. I'm guessing those 2 things (D-Zone more than body) are probably limiting his call-up opportunities more than anything. If you struggle in the D-Zone, I can't see Peters playing you (which is why Murphy's in Charlotte also).
Still, it's nice to see him progress and think it will be interesting next year. I'm guessing that Faulk, Hainsey, Wiz, Hanifin, Slavin and Pesce have the inside track on the top 6 next year. Fleury will probably start in the AHL so that could leave Carrick and Murphy for the #7 spot?
