These remarks are from his interview with ESPN's Matt Barrie. As far as I know, this is the most recent set of official comments from him, which appear to have been made yesterday.
On the quarterback battle...
"You watch Tyrone and he takes off fast, he just comes out racing, and then you see Buechele just making a move. It's been back and forth every single day, each and every week. It's been fun to watch because you have two competitors and they want to be the quarterback here. The quarterback that the players feel the most comfortable with, but who has the team and can get the pulse of the team, that will be the guy that leads this program."
On who the quarterback will be...
"I've had that conversation, here it is on Saturday. I don't even have to say anything. I don't even have to tell one of them, I think they understand who it is."
