Air Force athletic director Hans Meuh fired coach Jeff Reynolds so he could restore some fun to the program. The Falcons were all smiles Saturday. "Everybody's on a high right now," said Michael Lyons, whose 27 points and four steals led Air Force to a 58-56 upset of San Diego State (No. 15 ESPN/USA Today No. 13 AP), the Falcons' first win over a ranked team in 20 years.
