For the third consecutive week, the (8-5) Kansas City Chiefs enter their next game hoping to begin a winning streak that will help them earn the AFC’s No. 1 seed. Two weeks ago, six straight wins would have clinched it. A week later, five wins (and a little help) would have been enough to secure the top seed. But after two straight losses (among four in the last six games), the Chiefs are in a difficult situation: without four wins to close the season, the top seed is almost unattainable — and even with four, the team will still need substantial help.
