One day when the centaurs are out drinking to celebrate winning a hard game(as evidenced by the fact that even Shane is tipsy) someone, probably Troy or Bood asks Shane if it doesn't bother him that even when theyre being all lovey-dovey Ilya still calls himself the best hockey player ever and Shane is just drunk enough to confess that one time while trying to be romantic Ilya called him the best and he was so turned off he had Ilya promise to never do it again(with the sole exception being sexy affirmations time but the team doesn't need to know that). They suspected it before but now everyone is 100% sure hockey is foreplay for them
