Are Sneed and McDuffie the best cornerback duo in the NFL now? Not including safeties, just outside corners.
The only pairs I think could challenge that assertion are Ward + Newsome in Cleveland and of course Sauce and Reed on the Jets, and we'll see about Howard + Ramsey in Miami when Ramsey returns.
There are some young duos that look promising but aren't quite there yet, like in Seattle or NE
