After graduating, he entered the 1998 NFL draft and was signed by the Arizona Cardinals. He played safety for the Cardinals.
Four years later, in May of 2002, he turned down a contract offer of $3.6 million from the team to enlist in the U.S. Army. He told friends and family that he enlisted because he was deeply affected by the 9/11 attacks.
