Former USNA hockey dad here. Everyone who wants to try out is given the opportunity. As stated, most of the varsity squad has played AA/ AAA, junior, or high level HS. Plenty of room for the not quite ready for prime time guys on the D2 squad. Many move up to D1 after a year or two. As far as popularity goes? Friday nights are always better attended. If there is a home football game, Saturday nights are pretty lightly attended since everyone except the hockey players have to go. The picture A6E Dad put up is the Army game, and yes, McMullen is rockin'. As a dad that watched his kid play AAA most of his playing days, I can say that the D1 games are really fun to watch. Tons more skill than HS hockey, but not quite NCAA. If you are asking as a player, I highly recommend it. Besides the hockey side of it, my son really enjoyed the break from the daily USNA grind, as well as the travel away on the weekends. If you can balance the academics and the athletics.... go for it.
