The Chargers promoted Hal Hunter to offensive coordinator/offensive line and named former Colorado State Head Coach Steve Fairchild as senior offensive assistant/special assignments Tuesday, the latest of several changes to the coaching staff. “Hal has been an important part of our offense since I’ve been here,” Head Coach Norv Turner said. “He has a complete understanding of what we want to do in the run and the pass.” Hunter spent the last six seasons as offensive line coach in San Diego.
