Rebuttal to most posters in this thread (excerpts from Martinez UT bio):
Martinez mentored Cameron Sutton, who became a shutdown corner and set the school career record for passes defended (37) before being selected in the third round of the 2017 NFL Draft by the Pittsburgh Steelers.
Martinez’s defensive backs averaged over 13 interceptions per season during his first stint at Tennessee, and his 2014 squad notched 16 picks to rank No. 15 nationally and third in the SEC. Nigel Warrior (2016) and Todd Kelly Jr. (2014) both earned spots on the SEC All-Freshman Team under Martinez’s tutelage.
With Martinez on staff, the UCF Knights defense allowed just 22.7 points per game in 2018 and ranked sixth in the nation with 28 forced turnovers. UCF racked up 8.2 tackles for loss per game – fifth-most in the nation – while tallying 29 sacks. Sophomore defensive back Richie Grant led the way with six interceptions, which was tops in the AAC and No. 3 in the nation. Second-half adjustments marked a key to the Knights’ success as opponents scored just 8.5 points per second half, including 3.3 points per third quarter.
Martinez helped push the Knights to a No. 34 total defensive ranking in 2019—59 ranking spots better than in 2017, the year before he arrived in Orlando. The UCF pass defense yardage average fell below 200 yards for the first time since 2014—as the Knights improved their NCAA ranking in that category by 83 slots over two seasons.
The UCF secondary helped the squad lead the nation in tackles for loss per game in 2019 (9.08), while ranking third in team pass efficiency defense (108.86) and fifth in third-down conversion defense (0.293). UCF’s passing yards allowed figure in 2019 (199.5) marked the best for the Knights since 2014. The defense also ranked third in the nation in passes defended (78) and fifth in opponents' yards per play (4.57). Among AAC teams in 2019, UCF was No. 1 in third-down defense, yards per play allowed and pass efficiency defense.
