I know that Yates knows the offense, has more experience and that Jones is still raw, but Jones is impressing with the Chargers and Yates looks terrible in practice and was even worse in the game.
Also did they just give Taiwan Jones, Cardell Jones old jersey? Having a RB wearing #7? I'm thinking they didn't want to make a New Jersey for a guy that was going to get cut and they gave him an old one that was laying around.
