Bihr, who is retiring from coaching after 25 years, was honored prior to tonight's opening tip-off.
The Lakers overcame an early deficit to take a 34-27 halftime advantage. Oswego pulled away in the second stanza and cruised to the 18-point victory.
Ahmad Mims and Mat Burridge led the Lakers with 15 points each. Dave Ponza added 12 points.
Senior Jon Allport-Cohoon led Buffalo State with a career-high 21 points on 9-of-15 shooting from the field. Dion Mozelle had nine points and seven rebounds.
Buffalo State will wait for the outcome in tonight's Fredonia/Cortland game to learn its SUNYAC playoff fate. If Cortland wins, Buffalo State will play at Potsdam on Tuesday. If Fredonia wins, the Bengals will be out.
