This is what McNair said
So what are the chances, that the tests he passed for the last 15 years weren't as critical as the test administered by the NFL?
What if he was taking something that could give a false positive. He was told before, "hey, you'll test positive if you take that stuff" But in the past, he never tested positive, so figured it was just urban legend. LIke Andro... can you really test positive by taking androstenedione??
I've never seen the list of banned substance, I'm not saying Cushing took androstenedione. I'm saying would it be possible, that he took something that is not on the banned-substance list, but would trigger a positive test result for something that is on the banned substance list.
