He recorded 236 carries for 1,889 yards and 37 touchdowns as a Running back his senior season, with nine 100-yard rushing games.

Although he was an offensive and long jump star in high school, Reynaud only received scholarship offers from Indiana and West Virginia.

Reynaud did not participate in any games his true freshman year due to grades, but was not red shirted.

During the 2005 season, Reynaud was accompanied with freshman-stars Pat White and Steve Slaton, and sophomore fullback Owen Schmitt.

In the Sugar Bowl win against the Georgia Bulldogs, Reynaud scored in the first quarter with a three-yard reception and a 13-yard reverse-run, and totaled 48 yards receiving.

On January 10, 2008, Reynaud announced he would forgo his senior year (regained due to being a prop player) and enter the 2008 NFL draft.

Later in week three against the Detroit Lions, Reynaud set a franchise record by returning a 105-yard touchdown on a kickoff in the 4th quarter.

During the same game on a punt return, Reynaud threw a lateral pass to cornerback Tommie Campbell which resulted in a touchdown.

On December 30, 2012, against the Jacksonville Jaguars, Reynaud became the 13th player in NFL history to return two punts for touchdowns.

Reynaud holds the dubious distinction of scoring the fastest in an NFL game, albeit for the opposing team.

Originally ruled a touch back, head coach Mike Tomlin challenged that, although Reynaud's movements were minimal, the ball clearly exited and re-entered the end zone.

On October 21, 2013, after muffing a punt that resulted in a San Francisco 49ers touchdown and negated a potential Titans comeback in the fourth quarter, Reynaud was released from the team.

[12] Reynaud was signed by the New York Jets on December 3, 2013, after return specialist Josh Cribbs was placed on the injured reserve list.
