He knocked up his girlfriend. According the the BYU Honor Code- a document that he signed and agreed to before he came here, he agreed to not have premarital sex.
We have lost a lot of athletes this way because they think they're above the Honor Code, but one thing I'm proud of my university for is losing at the cost of maintaining integrity. We lost Harvey Unga from our football team, and a few other players throughout the years.
I agree, BYU is probably going to tank in the tourney, but I'd rather them do the right thing than win a championship. As hard as that is to say.
