Here’s what Bronco said, via Jeremy Mauss at Mountain West Connection:
“I’m going to try to stereotype as best I can, so I can protect (the recruit’s) family and BYU. Usually when a young man who is LDS – a member of our church – has things presented as clearly as he had it presented to him and chooses not to come, there usually is a reason they don’t want to come… and it is usually not football-related. And so Manti chose a private institution, with a religious background without truly the same semblance of rules, or an honor code, like BYU has… My guess is there was something that he didn’t want about BYU and chose elsewhere.”
