Pac-12 notes: Colorado reverting to old form, a year after winning South title

Coach Mike MacIntyre and the Colorado Buffaloes wanted to prove the football program’s success was something other than a one-year phenomenon, but that’s how it looks in Boulder these days.The Buffs have lost to Washington, UCLA and Arizona to begin Pac-12 play, in defense of their South division title. Colorado is not out of the race, with games to come against USC and Utah, but it would take a big rally for the Buffs to win the South again.Colorado lost 45-42 to Arizona last weeken
