In a release from Texas, Mac Duff said:
"I appreciate the opportunity to be a part of The University of Texas football program. I have enjoyed not only working with the linebackers, but my association with the entire football team and staff. The linebackers are a great group of young men and their future is bright. At this time, I'm going to pursue some other professional opportunities. I want to wish The University of Texas team the best in 2008."
Mac Duff's defense finished near the top in stopping the run, giving up just 93.4 yards per game on the ground (No. 8, nationally), but his defense also finished near the bottom in stopping the pass, giving up 277.8 yards per game (No. 109, nationally). The linebackers, in particular, were the most criticized unit on the defense and Mac Duff received much of the blame.
In a release from Texas, head coach Mack Brown said that Mac Duff's resignation was due to "philosophical differences":
"Larry and I met this morning and he informed me that he is not returning for the 2008 season, sighting philosophical differences. Larry is a great coach and man and we appreciate all he's done for our program. We want to wish him luck in the future and will begin looking for a replacement immediately."
Mac Duff, a 36-year coaching veteran, came to Texas after spending the previous four seasons as special teams coordinator for the San Francisco 49ers. He joined the 49ers after his second stint at Arizona where he served as the Wildcats' defensive coordinator in 2001-02. Prior to his second stop in Tucson, Mac Duff spent four seasons as the special teams coach for the New York Giants from 1997-2000.
