He has hard feelings towards Kalani, but he also understands that he wasn't Kalani's choice. The head coaching job came with conditions and Ty was one of those conditions. I believe this was a terrible mistake by Holmoe and certainly one he wouldn't make again. Ty has harder feelings towards the administration as promises were made, but not kept.
I know that Ty is a lot more willing to cheer for BYU and Kalani than his wife is.
I think (just my opinion) that everyone involved knows Ty would have been a much better QB coach/assistant OC to start off.
Really a sad blotch on BYU football.
