Kalani was hired to keep the seat warm as Ty gets his feet wet. No chance BYU loses Ty to another program. Everyone has always known TY's abilities as a coach and leader from his days at BYU to his mentoring of Brett Favre. I think Kalani is well aware that he is keeping the seat warm for a while.
I have nothing against Kalani and think he deserves this opportunity. But, it's Ty's job when he's ready.
