D-Petey may never be a big-time point producer on the blueline, but at 6'4 he'll probably ending up playing in the 215-220 range. More importantly, he's a nasty piece of business in his own zone. You could see it at the World Juniors, and during his brief stint with Abbotsford.
And looks to me that his mobility and skating aren't a huge red-flag, and his work in front of his own goal is intimidating at times. NHL teams will usually always make room for a d-man with that kind of pedigree in their bottom three. And after season or two in Abbotsford, who knows? Maybe he trends even higher than that.
D-men are notoriously late-developers. One of the guys the Canucks have playing on their roster this season--Vincent Desharnais--is a classic example of that. I'm optimistic we'll see an everyday d-man in D-Petey by age 24 or 25.
