Geno Smith isn't on the Lions, Dolphins, or Vikings. We've beaten 4 teams that are top 5 in the league in sacks. KC is no different than any of them. They have a strong run game(Miami), a weak passing game(Jets), an average run defense(Vikings), and a good pass defense(Dolphins/Vikings/Lions).
KC shouldn't pose any more difficulty than those games. They're certainly not going to show our Oline a defense with talents it hasn't seen before. If Orton can complete passes against the Jets' Dline than he can do it against an inferior Chiefs'. And Jamaal Charles? We've already faced the #2 ranked, #4 ranked, and #9 ranked rushing yards RBs this season. Charles is ranked 19th and has only been averaging 12 carries a game. Not super worried about him.
The Chiefs are not just beatable, they're whoopable in Ralph Wilson Stadium.
