Yes.... They've got a great pass rushing duo (Houston/Hali), a monster in the middle of the D-line (Poe), good DB play (Smith/Peters/Berry), a good running game, a legit WR (Maclin) and a legit TE (Kelce). They ended the season at #3 in scoring defense and #9 in scoring offense. They beat the **** out of the Patriots last year, beat the **** out of the Broncos in their second game this year, and have won 10 straight games.
With the possible exception of the Seahawks, the Chiefs are the team in the league that I'd least like the Patriots to face right now. Between matchup issues and general unknowns, it's just a game I'd prefer be avoided.
