During the 2005
College Football season, Thomas saw action chiefly on special teams (in all 12 games) and also as a reserve halfback (in 10 games). As halfback he rushed 63 times for 248 yards with a total of five touchdowns. On special teams, he made a total of 132 appearances throughout the season with seven tackles. In 2006, he was moved to the position of linebacker because of his speed and physicality with Coach
Charlie Weis's blessing and was appointed captain of special teams. He proved valuable to the Irish as a flexible player with his ability to play both offense and defense. Thomas moved back to halfback for the 2007 season and was named a captain along with
Tom Zbikowski,
Maurice Crum Jr., John Sullivan, and John Carlson. He served primarily as a goalline back and led the team in rushing touchdowns. ==Professional career==
