Mack Brown made an unprecedented move when he decided to change defensive coordinators last weekend, reassigning Manny Diaz and replacing him with Greg Robinson after the Longhorns surrendered a school-record 550 rushing yards in a 40-21 loss to BYU.
With Daje Johnson sidelined with an ankle injury, Texas needs senior wide receiver Mike Davis more than ever. Although he's battled drop problems his entire career, Davis is enjoying a productive senior season so far.
Texas needs more out of its offensive line, arguably the most experienced unit on the team and the most seasoned offensive line in the country. The Longhorns struggled in short yardage situations and pass protection in last week's 40-21 loss to BYU.
After going 7-6 and delivering the program's first bowl win in four years, Ole Miss head coach Hugh Freeze signed one of the five best recruiting classes in the country. It was a group that included the nation's top wide receiver prospect (Laquon Treadwell), top offensive lineman prospect (Laremy Tunsil) and top prospect at any position (Robert Nkemdiche).
Senior quarterback Bo Wallace has been impressive in his second year as Ole Miss' starting quarterback and will be looking to atone for a subpar performance in Texas' 66-31 win over the Rebels in Oxford last September.
While Robinson helped the Denver Broncos win a pair of Super Bowls and the Longhorns to win a Rose Bowl, he also won only 10 games in four years as Syracuse's head coach and struggled as Michigan's defensive coordinator in his last job.
It's not a good thing for Texas that Anthony Fera has gotten a lot of work in the punting game but the senior transfer from Penn State has taken advantage of those opportunities, averaging nearly 44 yards per punt this year.
Protecting whoever it is plays quarterback this week -- David Ash if he's healthy, Case McCoy it's not -- will be paramount for the Longhorns this week after their offensive line let them down in a lopsided loss to BYU last Saturday.
