Yeah this is one of my biggest questions because they did just extend Chung. There obviously is still a place for him to excel in Cover 3 Robber, which is basically the same role he had last year and a coverage the Pats played a lot of with Rodney Harrison.
But if their corners need lots of help and they have to go more Cover 2, you’re going to see a lot more of Duron Harmon I think. I still don’t think Chung is incapable of playing back, at least in Cover 2. He’s just not a centerfielder in Cover 1.
There’s ways around it, but they’re not going to be a full zone team and there are a number of big receivers they know they’ll have to deal with – Demaryius, Decker/Marshall, even Sammy Watkins is 6′1″, Dez Bryant. Those matchups are the ones that appear to be problems at this point in free agency.
And embracing the mystery is always the way to go at this point in the offseason. We can panic about holes/potential holes in mid-May.
