Damn I remember really losing my **** when the Flames drafted Reinhart when Kabanov was still on the board. Happy that turned out, but it sucks to see someone with so much talent not turn out.
I think that's the problem. In hindsight, I don't think Kabanov had that much overall talent. He was a great stickhandler, but that's about it. His shot (in terms of both velocity and accuracy) wasn't very good, his hockey sense/IQ didn't seem very high, his skating was average, and his compete level was below where it needed to be.
For example, if a guy like Yakupov doesn't pan out, he'd be an example of "so much talent" going to waste. Because he's great in so many areas. Kabanov had some nice dangling ability, but nothing else ever stood out as elite.
People were just wowed with his ability to stickhandle, but being "so talented" involves being good at so many more aspects of hockey than just dangling. It's like if you took a checklist of attributes for a hockey player such as shooting, passing, stickhandling, positioning, work ethic, awareness, skating, physicality, etc., the only thing you could put a checkmark beside was stickhandling.
