Not true.
As far as going to Broncos Games, it would depend a lot on the circumstances. You will be issued a certain number of weekend passes (and can earn more). If you plan right, can borrow a car from an upperclassman, and get tickets, it would be possible to get this to work. Another option would be to have an awesome sponsor family with season tickets who would take you to a Sunday afternoon game since you don't need a pass to go to your sponsors. An 1100 Sunday game would be good in order to give yourself time to get back to the Academy. A Saturday night game would be even better since you wouldn't have to push it to be back to USAFA by 1700 hrs on Sunday.
Our son did make it to a couple of Broncos games and a few Rockies games while he was out there, but I don't really remember which years he went.
It would definitely not happen until after BCT...probably later in the NFL season.
Obviously without a 2014 NFL schedule in hand there is no way to know if it would be possible right now.
