For the first time in the 2019 season, the New England Patriots find themselves in a must-win situation when they take on the Kansas City Chiefs at Gillette Stadium in Week 14. No longer the No. 1 seed after losing to Houston in Week 13, New England will need to win to have a greater chance at securing home field advantage come January. Kansas City presents an explosive offense for a Patriots defense that let up 40 points the last time the Chiefs came to Foxboro in a 43-40 Week 6 win last season.

Here are six things that New England fans should about Kansas City before the two teams meet up Sunday.

1. As Patrick Mahomes goes so does the Chiefs offense.

What has been the key for opposing quarterbacks to find success against the Patriots vaunted defense? Possess a strong arm and a speedy pair of legs. In Week 9, Lamar Jackson led Baltimore past New England with 61 yards and two rushing scores. Last week, Houston quarterback Deshaun Watson threw three touchdown passes in a win over the Patriots. Watson’s known effective running game opened things up through the air.

It’s more of the same this week in Patrick Mahomes for the New England defense. Mahomes missed a pair of games earlier this season and has been effective on the ground since his return. Last week, he ran for 25 yards and averaged eight yards per carry to go with a rushing score. In Week 11, he finished with five rushes for 59 yards. Mahomes is more successful in the passing game when defenses have to factor in his ground game.
