In his time at USC, he helped develop former Trojans and current NFL stars Marqise Lee, Robert Woods and Nelson Agholor. Over the past two seasons, Martin has led the USC offense to consecutive decades-long highs in total yards per game with 477.1 yards in 2016 and 481.1 in 2017. Martin’s name came up in a few head-coaching rumors this off-season, including at his alma mater of Tennessee. The Volunteers ended up settling on Alabama defensive coordinator Jeremy Pruitt after an extended head-coaching search. Defensively, Pendergast has re-energized the Trojans. In 2017 USC tied all other FBS programs at the top with 46 sacks led by senior Uchenna Nwosu, who tallied 9.5 sacks on the season. After being defensive coordinator for USC for the 2013 season, Pendergast left for two years to serve as the linebackers coach for the San Francisco 49ers. Since he returned for the 2016 season, USC has been one of the strongest defensive units in the Pac-12. Off the field, both Pendergast and Martin have been instrumental in keeping USC atop the college football recruiting world. Both of the recruiting classes that these coaches have been a part of shaping, 2017 and 2018, have been ranked among the top five in the nation according to 247sports.com.This season, 247 ranked Tee Martin as the second best recruiter in the Pac-12 behind USC linebackers coach Johnny Nansen.
