John was just an average player but a pretty good long-snapper. I think Brett was just living off the reputation of his older brothers while he was at BYU. He seemed less remarkable than John.

"I'll admit, BYU football in the 80s was very respectable. Very cool, classic Lavell. Alot of great players. Mcmahon, Young, Detmer. Very good teams."
