The NFL is threatening to punish players who won't cooperate, presumably on its terms, with an ongoing PED investigation. The players' union says there's no credible evidence for the league to proceed.
Training camps begin in a few weeks, and unless there's agreement on what's legit from a recanted Al Jazeera report, there could be a major controversy before games are even played.
