You have to think that the NFL and whatever testing service it uses know of hundreds of different substances, ones that would – and wouldn’t – trigger a positive test. So it seems really strange that Edelman reportedly tested positive for something that wasn’t recognized.
There’s one other question: if the substance is unrecognizable, as Breer was told, why did the NFL suspend Edelman for it? Are they assuming guilt first, and will reverse course later if it’s not found to be a performance-enhancer?
