The Texas football team shaking things up after an embarrassing loss on the road to BYU. Manny Diaz has been fired as Texas defensive coordinator, former UT co-defensive coordinator Greg Robinson has been name to the position. This coming on the heels of last night's loss to BYU, which the longhorn's defense had one of its worst performances in the school's history. It's no surprise that the Texas football team dropped out of the top 25 polls after Saturday's 40-to-21 loss at BYU. Diaz will be reassigned to another position within the athletics department.
