Ben certainly has friendships and/or connections with people in the program, or have been in the program... from players to coaches to some with admin roles.
So while this may be considered somewhat inside info, it really isn't. Nobody at BYU except TH, Wort, and maybe a couple of others has any real clue... and I'm guessing they probably don't even really know at this point. And if they did know anything, they wouldn't be saying anything to anybody else, that's for sure.
Criddle is a really good guy. Like him a lot. But remember that Ben was a player with a lot of heart, a lot of confidence, but in the end was just an average performer at best... in other words... don't put a lot of stock into his confidence. It's more wishful thinking than anything.
