The Jaguars face a daunting challenge on Sunday at TIAA Bank Field against the Kansas City Chiefs, the top seed in the AFC last season who lost to New England in overtime in the AFC championship game.

The Chiefs beat the Jaguars 30-14 in Week 5 at Arrowhead Stadium last season, taking advantage of four Blake Bortles interceptions. Kansas City had five sacks.   

Here are seven things to know about the Chiefs.

Three wins away from milestone

The Chiefs have won the last four games in the series against the Jaguars, including all three under coach Andy Reid, who needs just three wins to pass Chuck Noll (209) for sixth most in NFL history. Reid’s first victory with Kansas City came in Jacksonville when the Chiefs beat the Jaguars, 28-2 to open the 2013 season. Only five players on the Chiefs roster remain from that game – punter Dustin Colquitt, offensive tackle Eric Fisher, fullback Anthony Sherman, tight end Travis Kelce and guard Jeff Allen; The Jaguars' lone remaining player is defensive tackle Abry Jones. Reid’s career record is 207-138-1 in 21 seasons as a head coach. He is 65-31 with the Chiefs in six seasons. Under Reid, the Chiefs have made the playoffs in five of his first six seasons.

Top offense

Kansas City led the league last season in yards per play (6.84) and yards per game (425.6). The Chiefs were the league’s highest-scoring team, averaging 35.3 points, the third highest in NFL history.

Defensive changes

The Chiefs' high-powered offense got most of the attention last season, but their defense experienced the most problems. The Chiefs ranked 31st in total defense in 2018, surrendering 405 yards per game. That prompted changes, with Reid hiring Steve Spagnuolo to take over for defensive coordinator Bob Sutton. Their biggest new player addition is safety Tyrann Mathieu, who signed a three-year, $42 million free-agent deal after playing for the Houston Texans last season. The Chiefs hope Mathieu will improve their secondary, which allowed 273.4 yards per game passing last season, the second highest in the league.

MVP Quarterback

Quarterback Patrick Mahomes became only the third player in NFL history to throw for 50 or more touchdowns in a season in 2018, joining Peyton Manning (55 in 2013) and Tom Brady (50 in 2007). But the Jaguars were the only team last season he didn’t throw a touchdown pass against. Mahomes, who ranked second with 5,097 passing yards, was the league’s MVP last season. 

Former Jaguars TE

Tight end Blake Bell, who played for the Jaguars last season, made the Chiefs’ 53-man roster. In Jacksonville, Bell played in 10 games, which included four starts in 2018, and had eight catches for 67 yards.

Series record

The Chiefs-Jaguars series is tied at 6-6. But Kansas City is 2-4 in games played in Jacksonville.

Big-play receiver

Tyreek Hill has 16 touchdown catches for 50 or more yards after his first three seasons. In last season’s 30-14 victory against the Jaguars, Hill made four catches for 61 yards. On Friday, Hill agreed to a three-year, $54 million contract extension with the Chiefs.
