08:20 AM ET 03.10 | Kellen Moore is 38-2 in his college career, but he returns to the football field in transition mode. Moore said Wednesday that it was difficult for him to lose coach and friend Bryan Harsin to Texas but he expects the change to help him. Harsin, the Broncos' offensive coordinator and quarterbacks coach the past five years, left in January to become the co-offensive coordinator at Texas. Former wide receivers coach Brent Pease replaced Harsin as Moore's mentor. ... "For me it's probably good just because I've been with Hars for four years. We're on the same page. We understood each other. We've kind of been doing the same thing for a little while. It always kind of sparks you when you've got something different."
