I think we're seeing a combination of a lot of things: 1. The OL is doing a much better job. I think they've altered their assignments and made it easier for them to hold their blocks since they're using the TE/FB to clean out the LB in a few formations. Something can be said of the OL needing some time to get their timing down as well. 2. CJ is running with purpose. He's hitting it up in there and getting what's there and finding, sometimes, he's breaking through. There's much fewer negative runs. He's making people miss. I personally think his problem was more between the ears. He's probably lost a little speed but what he has is more than 95% of RBs in the league. The question should be will he do enough to earn another season? Right now, I think it's 50/50.
