Let's be real here for a second. If the Raiders made no changes one would expect them to vastly improve for next year because of the problems they went through last season. If those problems come up again this season you might as well throw in the towel on Carr or the Raiders ever being good again. Doug Martin is washed up and done but I highly doubt the Raiders will put much faith into him. And Nelson may be past his prime but he is undervalued if people think last season when he had a nobody backup QB throwing to him is what his value really is.
