Let's just say for the sake of discussion that Landry's clean.
But if the NFL decides that they believe he's using PEDs they can make life miserable for him, visiting him any time, numerous times, and demanding that he provide a witnessed sample.
In a worst-case scenario, the NFL's enforcement people could make life miserable for someone they suspect of using PEDs. In theory, if that person becomes irritated, ornery, and uncooperative, they could make his life even worse.
