"As we continue to find ways to build and improve upon our team through our evaluation process, it was imperative that LaMont and Ronald were on board," new coach coach Lane Kiffin said. "It was extremely important to get their contract situations settled. We look forward to working with both players, introducing them to the many changes we will have on offense, and including them in our new team philosophy as well."
