B.J. Raji, who is considered the top defensive tackle in this month's NFL draft, claims that he has not received notice of a failed drug test at the combine. "The biggest thing is trying to figure out how this started," Raji told The Press Democrat. "I couldn't understand how this rumor became such a big splash in the media when there was no evidence -- there was no substance to believe it. The last couple days, I was just trying to figure out: Who? What? Basically, why?"
