ok. i think they are new. 7 ECAC players (3 Yale, 2 Harvard, 1 Colgate, 1 Clarkson) and a few goalies (Can only remember Grumet Morris and Lenny) are ranked. Lenny is the 6th ranked goaltender overall and the highest ranked college netminder. The 3 Yale players are the 3 highest ranked ECAC players (8, 60 and 68 - i believe).

McKenna of SLU is also on the goalies list.
