Did you think this would be anybody else?
Peterson and Mathieu gave these two a good run from Arizona, but Seattle's Richard Sherman and Byron Maxwell are undeniably the best cornerback tandem in the league right now.
How much appreciation the rest of that elite defense deserves for their success is a good question, but there is no doubting Sherman and Maxwell are excellent players in their own right.
Sherman in particular has established himself as arguably the top cornerback in the league. He landed at the top of the cornerback list in Miller's NFL 1000 series this year, and PFF had him rated sixth-best in the league last season.
There is a reason Sherman led the league with 9.5 snaps per cover target—that is to say, he was targeted at the lowest rate in the league when he was in coverage—and was generally targeted the fewest times per snap played last season.
Maxwell, meanwhile, is no slouch himself.
The third-year cornerback intercepted four passes in just five starts last season after taking over for suspended Brandon Browner. He managed to rank 13th over at PFF, despite getting far fewer snaps with which to garner a positive score.
He was so good that Miller ranked him eighth at cornerback in the NFL 1000.
Yes, the Seahawks feature a fantastic front seven and arguably the best safety tandem in Earl Thomas and Kam Chancellor, but that shouldn't take away from this fantastic pair at cornerback.
It's no wonder the Seahawks are absurdly good on defense.
