Top guys bring it when it counts and WSI 15u is the biggest tournament these kids will do in their youth careers. Also they weren't all new players, 70% of that ECK team are the same kids he plays with every spring. It's much easier to put up points on a winter team when all of the offense is designed to revolve around you, especially the PP, so I disagree with your full season sample size.
Maybe he is hurt, maybe something else is going on, but he was outclassed heavily in this tournament. You can't throw out #1 in the country for a player that easily and not be able to back it up. Every kid on every team was playing with some new players and yet some of them absolutely crushed it.
There is nobody in the 2009 BY that is clearly pulling away from the pack right now besides Fitzhenry. Scuderi also making a good case that he is being held back and Dicunzolo as well. Dicunzolo was the star of the show for me although hard not to love Fitzhenry.
