Buck was in the bishopric at one of my BYU wards. He was the second most approachable church leader I ever had at BYU (I had one really awesome bishop). He knew the people in the ward. I had a buddy who was doing MMA fights at the time and Bro. Buck would always find us in the halls and talk to us about the latest UFC fight.
You could maybe disagree with some of his business investments, but as a person, he's awesome. I never knew anyone that knew him personally that didn't think so.
