Coaching changes have already begun this college football season, with Rutgers firing Chris Ash just a week ago. Now, Washington State is making a change on its defensive staff. On Friday night, the Cougars announced in a release that defensive coordinator Tracy Claeys was no longer with the program. 

"We appreciate Tracy's efforts the past year and a half and wish him the best going forward," Washington State coach Mike Leach said in a statement. 

On his personal Twitter account, Claeys noted that he had resigned because of on-field results and disagreements between himself and Leach. 

"I didn't resign for health or personal reasons," Claeys wrote. "The defense has struggled and I am responsible. We couldn't agree on solutions so the SPEED D is better with new leadership! I love the players and staff! They will finish strong! GO COUGS."
