Cornerbacks

My league uses two CB slots, makes it rough going. I've rolled with Joe Haden and Jason McCourty this year, and they have almost identical tackle numbers, with Haden contributing via Pass Def as well. I figure INTS are more a matter of chance for either of them than anything else, but I expected J McCourty to be more of a tacklemonster like he was last year; Is a change in scheme or dynamic limiting that, or should I expect him to get more opportunities going forward?

My watch list is topped by Leon Hall, Cortlandt Finnegan, and Rashean Mathis... but I'm also really optimistic to see Stephen Gilmore return this week. If I'm looking for consistency via tackles and pass def, should I be looking to defer to any of these names, over what I've got, going forward?

Thanks!

None of the FA names you listed excite me more than McCourty. Not sold that he's going put up the numbers he did last year but he has been a historically slow starter. I'd stick with him or play week to week matchups.
