not saying the rumors and what not are true, but in my experience, there are always two sides to EVERY story. For example, the narrative about Bronco ignoring him and going from hot to cold in three days without any explanation whatsoever doesn't pass the smell test. While it may have appeared this way to Mr. Gustin, he is plainly missing some facts from the BYU side. The story about the hazing incident is, well, also a little fishy.
In any event, this is largely academic at this point. I don't think anyone here likely has any more legitimate information. Rather than spread unsubstantiated rumors, let's all just move on.
Good luck to Porter and his family. I hope he finds a school that fits him well and enjoys success. I also hope he gets to fulfill that dream of serving a full-time LDS mission.
