New Mexico State football coach DeWayne Walker has left the Aggies to accept an assistant coaching job with the Jacksonville Jaguars. Aggies athletics director McKinley Boston announced Thursday that Walker will become defensive backs coach for the Jags. He went 10-40 in four seasons with the Aggies. "Unfortunately, I did not get the program as far as I would have liked from a wins and losses standpoint," Walker said in a statement. "But, we do have a better locker room, better kids and a better foundation for the program moving forward." Walker replaced Hal Mumme in December 2008, after serving as UCLA's defensive coordinator for three seasons. In the NFL, he has also served as an assistant with the Washington Redskins and New York Giants from 2002-05.
