I'm not that torn. I've never seen Justin have a bad game and usually he's having a ridiculous impact. How many other DL have you seen teams devote 3 OL to block like the Cards have done to Justin in the past? The answer is very very few. IE: The Reggie White's of the world.
I've seen Patrick have off games where he gets caught up in junk and takes himself out of position. The Chiefs game where Charles and Jones seemed to eat yardage at will against us was one of those games in particular. He just wasn't entirely on point and was a pretty big reason they were getting some of those chunk yards (by being out of position and getting sucked up into the blocking). To his credit I haven't seen him make too many more mistakes like that since then.
While Patrick might make few mistakes and is possibly the best tackler in the league, I never see Justin make mistakes and he's just as good a tackler at his respective position.
