I noticed that, too, but If I recall correctly he went on to provide examples of skills (passing over/under sticks through the neutral zone) that RPI could not do yet, or something to that effect, so it kind of left it open that his current players could improve. So I thought it was an attempt to add some motivation after the coach used plenty of other euphemisms to describe what he clearly thought was poor effort.
You are right, though, that this language might land differently with 20-22 year-olds that still have goals they want to accomplish in their hockey careers, than with the fanbase.
And sometimes the honest message needs a little twist to give the current players some belief. I've seen one college coach that took over an awful program admit to the remaining players during his first team meeting that he'd be bringing in better athletes, then said right after "but we are going to win with what we have in this room." That team went from last place in their conference to middle of the pack the very next season.
