he has connections to Kehl and Lavell.
Lavell wouldn't be that good at photoshop.
Bronco doesn't have that much time to be behind a computer.
Wrubell? Nope, seriously doubt it. Though that's the only possible guess... he would have connections to former players and Lavell... but I just doubt it.
Gunther is a Ute fan.
It's a former player. You hear his voice (briefly) at the end of the Lavell video... so he probably lives in Utah. Also, Kehl filmed his own video...
My guess is Bryan Kehl. But if not it's probably one of his teammates.
