The Dallas Cowboys thought they had nabbed a top-10 talent in the second round of last year's draft. More than a year later and he's reportedly failed his sixth drug test and is facing a yearlong suspension:
Linebacker Rolando McClain (10 games) and defensive end Demarcus Lawrence (four games) were popped for violating the league's substance abuse policy earlier in the year, as was Gregory.

Gregory was already facing a 10-game suspension for his fifth substance abuse violation.
Gregory failed a drug test at the NFL combine and failed two more last season before his last two, based on the NFL's drug-testing policy.
Gregory had 11 tackles and no sacks as injuries held him back last season. He'll be even further behind next year after this massive misstep.
