Individual play with the puck is emphasized at lower levels of hockey in order to develop skill, the thinking being that you don't become a good puck handler if you don't have it on your stick. So, it's basically encouraging "hero puck" pay. I never liked it, but that's what more experienced minds than me recommend. The problem gets to be when players don't flip the switch and start making the right play as they advance into higher levels of hockey(Bantams and up for me, certainly Midget/Junior).
Connelly looks like a guy who only passes when he has no other option. As one observer put it, he doesn't make players around him better, but worse. This can be fixed, if he is willing to, but it is hard to break old habits.
One weird thing about Connelly. He has decent height(just over 6'), but only weighed 160 at the Combine. That's really thin. The much maligned(about his size) Catton weighs 15 more lbs. than him, and is 2" smaller. Connelly looks like he needs to put on about 30 lbs. in order to survive in the NHL. That's a lot.
