Jaimie Thomas attended Bishop McDevitt High School, where he played football and basketball, earning a letter in both three times.
He served as part of a blocking unit for the state of Pennsylvania's best rusher, LeSean McCoy, who, in 2003, rushed for 2,561 yards in ten games.
[1] Thomas was named a SuperPrep All-American, PrepStar honorable mention, All-Northeast region, and first-team all-state player.
In 2005, Thomas saw action in all 11 games, including one start at the left guard position, and recorded three "big" blocks while allowing one sack in 162 plays.
[1] Before the 2006 season, head coach Ralph Friedgen suspended Thomas and tackle Jared Gaither from summer practice for two weeks due to unspecified team rules violations.
Thomas was part of the offensive line responsible for opening lanes for tailbacks Lance Ball and Keon Lattimore, who rushed for over 1,400 combined yards.
Scouts were reportedly impressed by his arm length, a 78-inch wingspan, which Thomas said "helps in pass-blocking more than run-blocking ... me being able to lock onto guys.
