Miami (8-4) has evolved from the NFL's worst-scoring defense in 2019 to the NFL's No. 2 scoring defense in 2020 (0.1 points behind the top-ranked Pittsburgh Steelers). But on Sunday, the Dolphins will face perhaps their biggest challenge yet in the coach Brian Flores era when Patrick Mahomes and the Kansas City Chiefs come to town (1 p.m. ET, CBS). "This is really going to test us to see how good we are as a defense," Dolphins safety Eric Rowe said. Fellow safety Bobby McCain added: "We know they've got really good players. So do we." With all the attention on the Chiefs' offense, the Dolphins' defense isn't a pushover. It's a respect game. Cornerback Xavien Howard leads the NFL in interceptions with eight and is a legitimate NFL Defensive Player of the Year candidate. Pass-rusher Emmanuel Ogbah is having a Pro Bowl-caliber season. Flores and defensive coordinator Josh Boyer can scheme with the best of them.
