Polamalu’s promotion is one of several coaching changes for UCLA, as the team overhauls its offensive staff following the departures of coordinator Noel Mazzone and quarterbacks coach Taylor Mazzone to Texas A&M.
Polamalu, a former USC fullback and linebacker, was the USC offensive coordinator for three seasons.
He was hired by UCLA before the Bruins' bowl game in 2013. Over the next two seasons, he coached Paul Perkins to consecutive 1,000-yard rushing seasons.
The team has also brought aboard Marques Tuiasosopo as quarterbacks coach, and is set to make Rip Scherer its tight ends coach.
Scherer, a longtime NFL and college assistant, had been UCLA's assistant athletic director for football. Tuiasosopo was the quarterbacks coach at USC.
