Early years
Thomas was born in Virginia Beach, Virginia. He attended Ocean Lakes High School in Virginia Beach, and he played for the Ocean Lakes Dolphins high school football team. He was named 2008 first-team all-state, all-region and All-Tidewater, and was a two-time first-team all-district selection. He set school records in career tackles, interceptions and defensive touchdowns. In 2008, he recorded a team-high 102 tackles, six interceptions, 11 pass breakups, and one blocked field goal as a team captain, leading the squad to a 12–1 record, while earning 2008 team defensive MVP honors. He led the team in tackles as a junior.

Thomas was also a track star at Ocean Lakes High School. He earned all-state honors competing in the 100 meters, and as the anchor of the 4 x 100 meter relay that placed seventh in Virginia. At the 2009 Beach District Championships, he placed first in the 100 meters (10.76s) and third in the 200 meters (21.78s).

College career
Thomas attended Syracuse University, where he was a member of the Syracuse Orange football team from 2009 to 2012. During his career, he started 43 of 48 games in which he played, recording 263 tackles, two interceptions and four quarterback sacks. As a senior in 2012, he was a first-team All-Big East Conference selection.

Professional career

Pre-draft
Thomas was projected by many analysts to be a mid-round selection, likely going in the third or fourth rounds. Although he had good coverage skills and was thought to be really tough, many scouts thought his lack of height would be an issue when covering tight ends. He was invited to the NFL Combine and performed well, but during his 40 yard dash, he fell. He was unable to perform the three-cone drill due to a hamstring injury but did make it up at Syracuse's Pro Day. Thomas was comfortable enough with his combine performance that he chose not to do any exercises, besides three-cone drill, at his Pro Day. He was also rated fourth among 177 qualifying strong safeties by NFLDraftScout.com.

Pittsburgh Steelers

2013 season
The Pittsburgh Steelers selected Thomas in the fourth round (111th overall) of the 2013 NFL Draft. The Steelers traded their third round pick in the 2014 NFL Draft to the Cleveland Browns in order to acquire their fourth round pick (111th overall) in the draft to select Thomas.

On May 16, 2013, Thomas signed a four-year, $2.61 million contract that includes a signing bonus of $453,152.

He entered his rookie season as the third-string backup to Pro-bowl veteran Troy Polamalu and Damon Cromartie-Smith. He made his professional debut in the Steelers' season opener against the Tennessee Titans and finished with two tackles. On September 22, 2013, Thomas had his first career start and finished the loss with one tackle against the Chicago Bears. On November 3, 2013, he had his best game of the season after he made a season-high 8 total tackles during the Steelers' 31–55 loss to the New England Patriots. During a Week 10 matchup against the Buffalo Bills, he suffered an ankle injury that sidelined him for the next two games. Before the injury, Thomas had been able to earn the backup strong safety position and mainly played the primary safety in the defense's sub packages. Veteran Will Allen was signed by the Steelers to substitute for Thomas while he recovered from his injury and when he returned he was unable to win his former position from Allen.

He finished his rookie season with a total of 29 tackles in 14 games and two starts.

2014 season
During the offseason, Thomas was invited by Troy Polamalu to train with him in California under Polamalu's trainer Marv Marinovich. He was the first player Polamalu ever invited. They used iso-kinetic training to focused on fast-twitch muscle fibers. He entered training camp battling Will Allen for the backup position behind Polamalu, and won the backup position after Allen was moved to the backup free safety position behind Mike Mitchell. In his second season with the Steelers, he was unable to receive prominent playing time and was mainly used as a gunner on special teams. During the 2014 season, Thomas played in 11 games, none as a starter, recording 5 solo tackles and his first career forced fumble at Carolina Panthers in Week 3.

2015 season
On April 9, 2015, Polamalu announced his retirement from the NFL, and Thomas was assumed to be the heir apparent. After a rough preseason, it was determined that Thomas would be the backup behind Will Allen. Thomas played sparsely during the season, registering just 12 tackles in 15 games.

2016 season
Thomas entered the offseason with an opportunity to regain the starting position after the Pittsburgh Steelers decided to overhaul their pass defense after ranking 28th in 2015. With former starting strong safety Will Allen gone, Thomas battled rookie Sean Davis and veteran Robert Golden for the starting strong safety position. He lost the job to Golden and was slated to be his backup to begin the regular season. He was placed on injured reserve on December 24, 2016.
