The University of Colorado at Boulder sponsors 16 varsity sports teams. Both men's and women's team are called the Buffaloes (Buffs for short) or Golden Buffaloes (acceptable, but rare).[1] "Lady Buffs" referred to the women's teams beginning in the 1970s, but was officially dropped in 1993.[1] The nickname was selected by the campus newspaper in a contest with a US$5 prize in 1934 won by Andrew Dickson of Boulder, Colorado. They participate in the NCAA's Division I (I-FBS in football), in the North Division of the Big 12 Conference. The University's current athletic director is Mike Bohn (since April 13, 2005). Colorado has won 22 National Championships in its history, with most in skiing. It was ranked #14 of "America's Best Sports College" in a 2002 analysis performed by Sports Illustrated.[2] In June 2007, the Buffaloes were placed under probation for two years and fined $100,000 for undercharging 133 student-athletes for meals over a six year span (2000-01 to 2005-06) resulting in the major infraction.[3] The football program, with 86 of the 133 student-athletes involved, also lost one scholarship for the next three seasons.
