I'm a pretty big fan of Borgesi... he won't get signed here, but he could be a guy down the road to watch. I think he's going to excel in college big time and reward somebody for taking a chance on a tiny defensemen. Slight chance he's Perunovich 2.0.
Cotton is likely a guy who ends up in Loveland. He broke out in a big way in his +1 year (IIRC led WHL defensemen in scoring), but just never took a step further than that. Not a great skater, not real smart either... but can contribute in the AHL now and might have a bottom pairing extra D future.
McClennon has a good shot at being a AAAA player, hope he finds his way in the org.
Roersma is probably my favorite invite. Kid has a fantastic shot, plays with energy and pace, good (not great) skater, plays a heady 2 way game. I expect that he'll impress in this camp. Should have been drafted.
