It has, but I have no way of proving that or even giving that credible support because nobody has said as much. However, Gregory had this problem before he ever arrived in Dallas and DLaw's problem is not weed. It's amphetamines. That's a substance used to improve your performance, not to get high with. It's very unlikely that if DLaw was using, he started when Hardy got here. He has a four game suspension which means that he has tested dirty multiple times. Besides, Other players have also been suspeneded for usage and they predate Hardy. I think it's a little too convenient to say it's Hardy. This problem exists and has existed for a long time all over the NFL.
