It could easily be even worse than that; the Colts appeared poised to march toward a touchdown until a J.J. Watt batted pass turned into an interception, and the Colts ended the half in field goal range as time expired.The Texans had just one good drive, but that ended with Deshaun Watson throwing incomplete into the end zone on fourth-and-1.Houston will get the ball first in the second half.

Only New England is among the top 10 in fewest points allowed.But the Chiefs, Patriots, Saints and Rams do possess the four most prolific offenses in the league. That's the first time the four highest-scoring teams play for the conference championship during the Super Bowl era.It's fitting one of those teams will win the Vince Lombardi Trophy because offense dominated in 2018.

Brady's Patriots are the only team of the four that didn't average at least 30 points, scoring 27.3. Kansas City led the way at 35.3 with Mahomes throwing 50 touchdown passes. Los Angeles was next at 32.9 and New Orleans averaged 31.5.Elite QBs aren't the only thing these teams have in common.

"That's what really presents such a great challenge because they've got a Hall of Fame quarterback and they got an elite running back, and they've got a great system."The Chiefs were in the middle of the pack on the ground during the season, but Damien Williams had 129 yards in a 31-13 rout聽of the Colts."Andy's an offensive coach, so the offensive plays they get on special teams and the offensive plays they get on offense, when you combine all of that together, it's a lot of firepower and a lot of explosive plays," Patriots coach Bill Belichick said of the Chiefs. "Andy's teams are always tough Pat McAfee Color Rush Jersey , well-disciplined. They don't make a lot of mistakes. They make you beat them, and that's hard to do because they're sound and he gets good players and he coaches them well and they're tough."Other than Belichick, each team has offensive-minded coaches. Payton, Reid and McVay earned their way on that side of the ball. The 32-year-old McVay is the youngest coach to win a playoff game.Both games are rematches from thrilling, high-scoring contests in the regular season.The Patriots (12-5) beat the Chiefs (14-3) 43-40 at home in October.
