Tretowicz graduated last spring. I think the same is true of Harvard's Teds (Donato and Drury), but I'm not altogether sure. The Canadians Ratushny and Manderville were junior and sophomore at Cornell last year, respectively. Ratushny probably would have turned pro this year anyhow, but Manderville (Calgary property) would likely have stuck it out for one more year. Speaking of Canadieans, don't forget Joe Juneau. He actually got his masters degree from RPI last year --- he's a class act academically and hockey-wise.
