My Top 3 prospects are easily Roy, Struble and Mailloux.
Caufield has graduated, but if not, I'd throw him in the mix with these three.
I was looking at Mailloux videos earlier tonight, and he literally looks like Denis Potvin out there.
He has a great wrist shot from the point, a powerful slapshot (although he could use it more based on the highlights, he seems to prefer his wrist shot, just like D. Potvin), he has a great first pass under pressure, he's a pretty good skater for his size, has decent stickhandling abilities, is very physical and can throw devastating hits, and he's 6 ft 5 and right-handed.
Just a matter of knowing if he has the hockey IQ, something which Potvin had in spades. Obviously I'm not saying he's gonna be a Potvin, who was a prodigy even in junior, but he does remind me of him stylistically.
Seriously, Mailloux is looking soooo good, he might have been worth the hassle.
