Miller played the best two games that I have seen a LB play since Taylor. Ware was also relentless. Arizona doesn't have players who can get to the QB like this, they have older players on the cheap and undersized lineman, like Minter and Golden.
Carson would do fine as a game manager with a stud defense, but he is more regular season numbers guy vs. huge game winning QB. That's not bad at all, it's really good actually, but it isn't elite, so unless Carson has a real defense I do not think he can win games by himself, he isn't that QB.
The good news, is the Cardinals if aggressive can fix these issues, the need a edge rusher and a real linebacker, dump Massie and Larson, the team is already improved. And let's mention Badger is back next year. The Cards will be top 5-6 overall, so they will have a chance.
Edit: I meant Rucker not Minter...But I also think Minter is a soft LB, who could be replaced as well, too bad Washington is ********, because that would solve that issue.
