When has he shown he's been a teir above others two years in row?
By scoring at rates that other players could only dream of. The fact alone that he actually IMPROVED upon his early 2ppg pace - which again is a huge achievement: all while leading his team to the memorial cup and being acknowledged by being named the league's playoff MVP.
I can't think of a single skill he can improve by yet another year playing among teenagers.
