Todd Graham called Mike Leach's comments "chickenshit" during the post-game handshake following the Arizona State-Washington State game Saturday night.
Deadspin captured the video, seen below.
Leach accused Arizona State of stealing signs this week, saying, ""I think they steal signs, and we'll have to keep an eye on that.... That is very unsavory practice they have, so we'll have to do what we can to defend it."
Graham and Arizona State AD Ray Anderson took exception to Leach's accusation. "We do everything exactly by the rules. Period," Graham told the Arizona Republic. "I'm not going to get involved in things like that that are ridiculous."
The conference fined Leach $10,000 for his comments.
When asked after the game, Leach chose not to answer.
Washington State won the game, 37-32, lifting the Cougars to 5-2 overall and 4-0 in Pac-12 play.
