Thomas' incredible showing netted him a third Defensive Player of the Year Award (tying the mark set by Kenny McEntyre for the most in AFL history); he was also named a First Team All-Arena selection (his fourth career appearance on the First Team). Thomas' resurgence helped the SaberCats to a 13–5 finish; they lost to the defending champion Arizona Rattlers in the first round of the playoffs. Thomas returned to the SaberCats in 2014. While his numbers dropped considerably from his 2013 campaign, he remained one of the league's best cornerbacks; in 2014, Thomas tallied 70.5 tackles (60 solo), 14 pass breakups, and 8 interceptions (one of which was returned for a touchdown) in a career-high 18 games. Thomas remained a key part of the SaberCats' top-ranked defense; despite this, he failed to garner any major awards in 2014. The SaberCats once again finished 13–5; while they won their first-round playoff game, they were again defeated by the Rattlers (this time in the Conference Championship game). Thomas did not re-join the SaberCats at the start of the 2015 season, once again fueling speculation that he had retired. During the offseason, San Jose had acquired AFL superstar cornerback Virgil Gray; this served to bolster the belief that Thomas' career had reached its end. During a Week 3 contest against the Tampa Bay Storm, Gray suffered a season-ending knee injury; days later, the SaberCats announced Thomas' return to the team. Thomas continued to play well; in 15 games, he recorded 41 tackles (34 solo), 14 pass breakups, and 6 interceptions. In 2015, the SaberCats' defense was historically dominant (allowing just 36.8 points per game, the lowest such figure in modern AFL history); the SaberCats finished the regular season with 17–1 record (tied for the best in AFL history). Thomas' SaberCats won their first two playoff games to advance to ArenaBowl XXVIII, where they faced the Jacksonville Sharks. During the game, Thomas recovered a Michael Lindsay fumble deep in Jacksonville territory; the turnover resulted, shortly thereafter, in a key score for the SaberCats. San Jose would go on to win the game, 68–47, to claim the fourth championship in franchise history; it was also the fourth championship of Thomas' career. Thomas was assigned to the Los Angeles Kiss on March 31, 2016. Thomas was assigned to the Baltimore Brigade on June 13, 2018.
