I have some Corona contacts and heard 3rd hand maybe a week or two into the season that Tanner's dad was still high on Ty and wanted McKee to go to BYU. Obviously that could have changed after a few more dreadful games. But your info from before the season is at odds with my info.
Could also be that they've changed their minds about BYU and now act like they felt that way even before the season. Who knows.
