"BYU head coach Kalani Sitake admitted that Mangum made the final selection a difficult one to make.

'It was a really hard decision because you have some guys who have good days and bad days," Sitake said. "Consistency was one thing we wanted to look at and both were really good consistently. We felt this was going to be right. Going into it, I think Tanner is way better than he was a year ago, just with that experience of being on the field. There are some things that Tanner brings to the table that Taysom can’t, and there are things Taysom does that Tanner can’t. For the team and where we sit right now, this is the right move for us.'"
