JACKSONVILLE Brian Burns Jersey , Fla. (AP) The Jacksonville Jaguars are finished with the Payback Tour.Now its on to a tougher challenge, a more high-profile matchup.The Jaguars (3-1) will play at Kansas City (3-0) next week a game that features the leagues top defense against one of the leagues most potent offenses.We pride ourselves on being a really good defense so this is a great challenge for us, defensive end Calais Campbell said following a 31-12 victory against the New York Jets on Sunday. We know theyve got firepower everywhere. Everywhere. Im looking forward to the challenge. This defense, we believe in ourselves, so this is an opportunity for us to go and see what happens.The Jaguars have put together four impressive defensive outings to start the season, allowing 324 yards against the New York Giants in the opener and then getting better every week since.New England (302 yards), Tennessee (233) and the New York Jets (178) scored a combined three touchdowns against Jacksonvilles vaunted defense. Two of those came off turnovers. New Englands first touchdown in Week 2 followed DJ Charks fumble near midfield, and the Jets lone touchdown Sunday also was gifted. T.J. Yeldon fumbled at the Jacksonville 29-yard line. Trumaine Johnson scooped it up and returned it to the 5 .Sam Darnold connected with Jordan Leggett in the back of the end zone three plays later.The Jets managed little else.The Chiefs should be more difficult to cover Greg Little Jersey , between speedster Tyreek Hill, fellow receiver Sammy Watkins, tight end Travis Kelce, running back Kareem Hunt and quarterback Patrick Mahomes.The secondary welcomes these games, Jaguars safety Barry Church said. We know theyre going to throw the ball all over the place, so as a secondary weve got to go out there, prove that were one of top secondaries.They have options at every level like slot, outside receiver Will Grier Jersey , tight end, running back and a quarterback that can throw it a hundred yards so thats going to be a great challenge for us. But I think we have the players that will step up and be ready for the challenge.Jacksonville had plenty of motivation the last four weeks: top executive Tom Coughlins first game against his former team (Giants), a rematch of the AFC title game (Patriots), a division game against the only team that swept the Jags in 2017 (Titans) and a third consecutive home game against the team that snubbed Doug Marrone for its head coaching job in 2015.Next up are the high-powered Chiefs.Weve got another game, a great team were playing next week, Jaguars defensive end Yannick Ngakoue said. Weve got KC, and thats what our focus is on now. Like I said, weve got to this win Christian Miller Jersey , enjoy it now. Its in the past.Here are some other things to know following Jacksonvilles win over the Jets:FOURNETTE OUTJacksonvilles biggest concern is the health of running back Leonard Fournette, who re-injured his strained right hamstring after missing the last two games. Fournette ran 11 times for 30 yards before leaving for good.Anytime you come back and youre ready to go and then all of a sudden you get injured again, its not a good sign, Marrone said.MESSAGE SENT?Marrone insisted he followed the chart, calling for a 2-point conversion after a fourth-down touchdown run in the final seconds of a lopsided game. Few believed him.Marrone was seemingly sending a message to the Jets , the team that passed on him three years ago and hired Todd Bowles.He doesnt like those guys, Jaguars defensive tackle Malik Jackson said. I dont know what they did to him, but he doesnt like them.Marrone said he had no hidden agenda or extra motivation Jordan Scarlett Jersey , which was hard to believe considering he took a subtle shot at Philadelphia Eagles coach Doug Pederson in late August.DARNOLD STRUGGLESJets rookie Sam Darnold was harassed early and often , getting sacked three times and nearly throwing three interceptions.Darnold completed 17 of 34 passes for 167 yards. He got little help since the 1-2 punch of Bilal Powell and Isaiah Crowell combined for 26 yards rushing.Weve got to make plays that were there, Darnold said. Ive got to make throws that are there and not think too much, take what they give me and well start to find completions and get into a rhythm. Bengals wide receiver A.J. Green spent the first eight years of his career playing for head coach Marvin Lewis, so hes making an adjustment this offseason with Zac Taylor now occupying the top job on the coaching staff.During an interview with Chris Simms, Green discussed the differences between the two men. Practices have a different energy with Taylor playing music something Lewis wasnt a fan of and favoring the offensive side of the ball, which is something that Green has found appealing during the early stages of the offseason program.Playing with coach Lewis, its all about the defense David Montgomery Jersey , Green said. You dont show up the defense at practice. But Zac is like, OTA one, were going to kick the defenses butt. Thats what we like to hear. I love the way he teaches. Hes not yelling at you, hes teaching every little detail and having you understand why we run it this way.Green said that he feels recovered from the toe injury that curtailed his 2018 season and anything Taylor teaches will look better with a healthy Green executing it come the fall.
