History

1980–83 – Orange Express

The 1980–81 Oregon State men's basketball season was arguably one of the best yet most upsetting basketball seasons in Oregon State history. The team was referred to as the Orange Express and was led by Beaver legendary coach Ralph Miller.

At the end of the regular season, the Beavers were  and entered the 48-team NCAA tournament as the top seed in the West region. They had a bye in the first round, but were upset in their opening game by #8 seed Kansas State 50–48 in the second round, at Pauley Pavilion in Los Angeles.  Miller was awarded UPI and AP Coach of the Year honors and Steve Johnson received All-American honors.

For three seasons beginning in 1980–81, OSU posted an overall record of , second only to DePaul's 79–6 record over the same seasons. The Beavers' record included a  home record at Gill Coliseum, including a school best 24 consecutive home wins.

However, NCAA sanctions followed these standout teams. The NCAA found that many players, from 1979 to 1983 were involved in improper arrangements with outside representative related to the purchase of complimentary basketball tickets and the receipt of other prohibited benefits.
