If I can recall, JuJu had 3 straight 100 yard games prior to that game and was top 5 in receiving yards. Also, yes, Marlon did cover AB for the majority of the game, but was it one on one? Obviously not because no one can cover him 1v1 but let's not ignore the fact that he did have help. I mean, we even had him doubled on the GL. On the other hand Carr was tasked with the responsibility with covering JuJu most of the time alone. That's a pretty tall task for anyone.
I'm not criticising Marlon by any means, I'm a big Marlon fan but I think people are overlooking the type of season Carr has had so far by saying he's going to get burned pretty much every game and I honestly don't think he's getting the recognition for the type of year he's having.
Also, it's no suprise Carr struggled against AB last year. Football is a game of matchups and CBs are prone to being exposed for their weaknesses just as much as anyone else.
To put it into better context, I'm not saying Carr is a better player, but instead of the fact that among all our CBs, that he's playing the best Football.
