I puta ia i roto i te kēmu kotahi i taua wa i mua i te whakatū i a ia ano hei kaihautū ki nga Cougars i te 2005<unk>06.

e te kapa Tampa Bay Lightning. I tua atu, i hanga e ia tona tīmatanga ao mo te kapa rangatahi Canadian i te 2007 Super Series, ka piro i tetahi whāinga i roto i te waru kēmu, engari kihai i taea te hanga i te kapa mo te 2008 World Junior Ice Hockey Championships.
