All that preseason hype surrounding Jacksonville's defense has come to a hasty halt.The Jaguars (3-3) allowed 802 yards and 70 points in consecutive losses to Kansas City and Dallas Youth Donte Moncrief Jersey , hardly the kind of performances Jacksonville's brash defenders expected when they opened training camp talking about going 16-0 and beginning a Super Bowl-or-bust season ."It's definitely uncharacteristic of us to get beat like that," safety Tashaun Gipson said Monday. "But at the end of the day, that's the only answer I can give you because that's what I believe in. Truthfully, deep down inside, I believe that we have the guys in here to turn it around."Nobody's panicking right now. We're frustrated. We're (ticked) off. Absolutely, but nobody's panicking right now and that's the thing. I don't know of any type of answer that people are looking for, know there's not a panic button. At least there's not a panic button in my mindset, and I don't see the guys in here" panicking.Jacksonville hosts Houston (3-3) on Sunday, with the winner getting at least a share of the AFC South lead as the season nears the halfway point.After the last two weeks, no one knows what to expect from Jacksonville.Injuries have ravaged the offense, with inconsistent quarterback Blake Bortles playing behind a third-string left tackle and without his top receiver, No. 1 tight end and bruising running back Leonard Fournette. Not coincidentally, the Jags have struggled to get anything going on that side of the ball.The bigger surprise has been the play of the defense, which is mostly healthy outside of nickel cornerback D.J. Hayden (toe) missing the last four games.Jacksonville is getting little steady pressure on opposing quarterbacks Youth T.J. Yeldon Jersey , creating few turnovers and giving up way too many rushing yards. Not only is the unit failing to carry the beleaguered offense, it's not even holding its own."We're looking at a lot of different things because obviously it's not good enough," Marrone said. "A lot of times people will want to (say), 'Is it this person?' If it was just as simple as this or this or this, you know, it would be easy. We would make those decisions and move on. But when you're playing poorly as a team or coaching poorly, you have to take a good look at yourself."Defenders pointed to miscommunication as the main culprit in a 40-7 loss to the Cowboys , guys unsure who's doing what after the snap. It was an uneasy feeling for a unit that returned 12 of its top 14 players from last year's team that finished second in the league in points, yards, sacks and interceptions."Is it a concern? Yes," Marrone said. "I'm not going to sit here and say, 'Hey, everything's fine. We'll be OK.' We're not. But in saying that, the only way you go ahead and get through this stuff is you've got to work harder Youth Ronnie Harrison Jersey , you've got to put more in, you've got to make the plays, you've got to be able to perform."It doesn't take a rocket scientist to know we're not a well-coached team right now, and that starts with the coaches; that starts with me first. I'm accountable to all of it."Marrone insisted there would be no knee-jerk reactions.After all, the team was 3-3 after six weeks in 2017 before winning of seven of eight to take control in the division.But given the sky-high expectations, especially for a defense that lined up with Pro Bowl players at every level, this start doesn't feel the same."When you look back and you go, 'Hey, we were 3-3 last year.' But it was a different type of 3-3. It's not the same as where we are right now. And right now we need to, like I said before, pull up those bootstraps."Jacksonville Jaguars vs. Kansas City Chiefs series history: AFC Showdown The Jacksonville Jaguars currently sit at 3-1 after dominating the New York Jets in Week 4. The Jags look like one of the NFL’s best teams right now, but arguably the toughest test of the season thus far looms for Jacksonville, as the team travels to Arrowhead Stadium to play the undefeated Kansas City Chiefs. It’s time for your favorite weekly history lesson (maybe?), as we review the all-time head-to-head matchups between the Chiefs and Jaguars. Similar to last week against the Jets Youth Jalen Ramsey Jersey , Jacksonville and Kansas City have a somewhat limited sample size, but a closely contested series history. Series historyAll-time regular season series record: Jaguars lead 6-5Postseason record: N/ALast Jaguars win: Nov. 8, 2009 (24-21)Last Chiefs win: Nov. 6, 2016 (19-14)Current Streak: Chiefs have won three straightBiggest Jaguars win: 24-10 (Nov. 9, 1997)Biggest Chiefs win: 28-2 (Sept. 8, 2013)Interesting takeaway: The Jaguars won six of the first eight meetings with the Chiefs, but have now dropped three in a row. Quick thoughts: Again, Jacksonville dominated the series early on by winning four of the first five and six of the first eight, but Kansas City was able to take advantage of bad Jaguars teams in the past few meetings to bring the series back to close to even. The Jaguars have fared better in Duval, getting four of the six series wins at home. The Chiefs have won three of five at Arrowhead Stadium, and Jacksonville hasn’t won in Kansas City since 2007.

Jacksonville out-gained Kansas City by 208 yards, and gained 15 more first downs than the opposition. However, the 2016 Jaguars were extremely turnover prone, and lost the turnover battle 0-4. Blake Bortles threw an interception and three different players lost fumbles. The Chiefs built a 19-7 fourth quarter lead, but a T.J. Yeldon touchdown cut it down to a five-point deficit. The offense would get one more chance to score, but could not do it.

Yeldon Jersey , 121 rushing yards, 17 first downsQuick recap: This one was not pretty. The Jaguars actually took a 2-0 lead early in the first quarter on a blocked punt safety, but it was all Chiefs after that. Kansas City took a 21-2 lead into the locker room at halftime and coasted through the second half. Blaine Gabbert threw two interceptions, including a fourth quarter pick-six to Tamba Hali. The Chiefs also won the turnover battle in this game, with the two takeaways compared to zero for the Jags. Jacksonville never threatened in this one and it was a typical game during the Gus Bradley era. Series By Decade: 1990s: Jaguars went 2-02000-2010: Jaguars went 4-32011-Present: Chiefs lead 2-0Quick thoughts: This series was fun for the Jaguars in the beginning, winning both matchups in the 1990s and winning two of the first three in the early 2000s. The Jags dominated from the first matchup in 1997 through the fifth all-time matchup in 2004, winning four of the five games in that span. The Chiefs have won four of the last six games overall and three in a row, though. This year offers us one of the most intriguing matchups of the 2018 season already, as two teams with a combined 7-1 record will face off with each other. Patrick Mahomes came down to earth a little bit this past week, but still had a good game and led his team to a comeback victory. It’s going to be really fun to watch Mahomes against the No. 1 pass defense in the league. On the other side, will Jacksonville’s offense be able to take advantage of Kansas City’s shaky defense? This is a true test for both teams. This is a tough one on the road for Jacksonville. How will the Jaguars fare?
