On April 10, 2007, the National Football League introduced a new conduct policy to help control off-field behavior by its players and preserve the league's public image. The policy, introduced by NFL commissioner Roger Goodell, implements a tougher, new personal-conduct policy, and under conditions of the previous policy handed down two of the harshest suspensions in NFL history for off-field misdeeds. Each player that has been suspended must reapply for reinstatement. The policy only applies to the player's personal lives and image in the public spotlight. The NFL conducts separate investigations for drug and alcohol abuse and performance enhancement.
