New C.U. football coach Mel Tucker has made a pair of important hires. Tucker has brought two coaches from the University of Georgia to Boulder. Jay Johnson will be Tucker's offensive coordinator, with Tyson Summers handling the Buffs' defense. Tucker was hired by C.U. after coaching the Georgia defense. The new coach also says that even though he grew up in Cleveland, the Denver Broncos are his new favorite N.F.L. team.
