That's what makes this so intriguing. Sherman is a guy who is very intelligent, and has never had an off field issue. He knows you can't beat or get around a positive test.
I find it really bizarre that they both tested positive at the same time....both starting CBs, and both in the middle of a playoff run.
The other bizarre thing is, they've both been very healthy, not coming off of injury or anything, and have both been playing at a very high level. They don't even need to cheat. The conspiracy theorist in my cries foul !
