He was a do-it-all player and became one of the best dual-threat QB's in East Texas, playing quarterback, wide receiver, running back, punt returner, kick returner, and defensive back as he led his team to a District championship his senior year.

Coleman was also a standout basketball player in which he was named the District and All East-Texas Defensive MVP his junior and senior year.

Along with Rickey Dudley (TE- Oakland Raiders), Coleman is one of the most influential athletes to represent Henderson High School in its history.

He was injured for most of the 2004 season, but as a senior in 2005 started all 12 games for the Horned Frogs' 11–1 Mountain West Conference Championship team.

In 2007, he was a regular on special teams and later in the season was included in some defensive packages for the Jets, including getting his first interception against the Miami Dolphins on December 2, 2007, and forcing a fumble during a sack in the last game of the Jets' 2007 season on Kansas City Chiefs QB Brodie Croyle.

Coleman made his first impact of the season by filling in for an injured Darrelle Revis against the New England Patriots in week 2.

Coleman impressed greatly as he was part of a Jets defense that did not allow a touchdown in the second half of the game, which is where he made his biggest impact.
