I don't count last year, so three (it just seems longer). We played in back to back ECAC championship games in the 13-14 and 14-15 seasons going to the NCAAs in 13-14. We had a very good team going into 15-16 and injuries and whatever struck. It wasn't until 16-17 that the doldrums set in (and 17-18 was actually not a bad season - it just wasn't a good one).
Maybe we already know, but Colgate made it official that McAvoy and McKechney are back for a fifth year. Women's hockey and Tennis have both recently posted their incoming classes so I would expect to see the Men's hockey out soon. Will be interesting to see if there are any differences from the Heisenberg list.
The incoming freshmen are already listed on colgate's roster
