2 games isn't a big enough sample size to really change any ranking. I've always said that I think Aldon will ultimately be the better player. I even said leading up the draft in 2011 that I'd have drafted him over any other player for the Pats. But Miller outperformed him in their rookie seasons.
I don't really care about rankings. Just pointing out that he's looked very good against the run. A lot of people said "he can't defend the run" last season when there was literally no sample size of him doing it since he wasn't asked to. Now he is, and so far he's been very good.
