I think this is it. And, on the flip side, if you're 6'4", you're going to get opportunities to try, and fail, and potentially grow and improve, that guys who are sub-6'2" will not get.
However, Levi is going to be a really interesting guy to watch, because his status as a 7th round pick playing behind a blue-chip 1st rounder in the FLA organization made him expendable. However, now that he was the centerpiece return for Buffalo's best player, he should be force-fed opportunity in this organization (see, e.g., Tage Thompson). Let's hope that, unlike Thompson, Levi can do something with that opportunity.
Personally, (based only on watching him play in the WJC) I really like the way Levi plays. He watches the puck really well and he uses his hands well. So, I'm very optimistic about those two things. And, Ed Belfour was 6'0". So, let's go with that.
