When HGH testing is implemented -- which could be soon according to some reports -- one columnist believes the NFL has another major substance issue it must face with the NFL Players Association.
USA Today's Jarrett Bell said next on the league's safety agenda should be a tougher alcohol policy.
The NFL offseason has featured three important cases involving alcohol. Two were in Denver, where the Broncos had separate incidents with front-office executives. Both were suspended by the team.
The third occurred right after the Super Bowl, when tight end Delanie Walker lost his aunt and uncle to a drunk driver. Their deaths spurred Walker to become a spokesperson for Mothers Against Drunk Driving as well as backing expanded DUI legislation in Tennessee, where he signed with the Titans.
