Back from drug ban, Cowboys' Gregory speaks of deeper issues

Randy Gregory understands the prevailing view that repeated use of marijuana is the reason the Dallas Cowboys defensive end has been suspended for 30 of the past 32 games. Now that he's on the verge of playing after a year away from the NFL, the former Nebraska standout wants people to know there are deeper issues of mental health that Gregory isn't comfortable discussing in detail publicly. ''I was self-sabotaging,'' Gregory said Monday in his first group session with reporters at training camp in California.
