If I'm reading this right, it really doesn't kick in for two more years ... so he's playing out his rookie contract then moving into the extension. Is this correct?
As for AD, Rams have all the leverage at this point. AD has to report by August 7th or he loses a year of FA. Even if he does, but won't sign, the Rams can franchise him for a couple of seasons after that, and I'm sure they would do just that. If the Rams are still offering to make him the highest paid defensive player in the league, then he either comes to his senses, takes the generous offer on the table and ends this madness. Otherwise, he's effectively placed on a series of one year deals with no long term guarantees. Your move, Aaron.
