From Buff Zone article:

Players often had high praise for Leavitt during his time with the Buffs, but junior safety Afolabi Laguda said on Friday that it's time to move on.

"Leavitt was one of the best coaches I ever had," Laguda said. "I love him, he knows I love him; and I know he loves me. I know he has a family and he had to do what is best for his family.

"The players make plays. No matter who comes in (to replace Leavitt), no matter what, we have each other, and that's what we're going to lean on. That's what the leadership this year taught us is how to bond together."
