For entirely different reasons http://www.kansascitychiefsteamonlin...omes-ii-jersey , young quarterback Patrick Mahomes and the Kansas City Chiefs' defense had shared most of the public's attention through the first four weeks of the season.Mahomes had been nearly perfect. The defense had been nearly inept.Yet in their biggest test so far, against a Jacksonville team that reached the AFC title game a season ago, Kansas City responded with its most complete performance. Mahomes was still humming against the Jaguars' top-ranked defense Sunday, while the KC defense piled up five sacks, forced five turnovers and returned one of Blake Bortles' four interceptions for a touchdown in a 30-14 rout ."The sky is the limit if we play all phases of the game like that," said Chiefs tight end Travis Kelce, who had six catches for 100 yards. "It's a special thing when you get a whole group of guys to come together for one goal. It's special and it's sure as fun as hell."The Chiefs (5-0) certainly appear to be special right now.They've already scored 175 points to set the franchise record for the five-game mark, while Mahomes threw for 313 yards against Jacksonville to give him a franchise-best 1,513 yards through Week 5.Mahomes has four straight 300-yard passing games, becoming the first QB in NFL history with four in his first six career games. He will try to set the franchise record with five consecutive games when the Chiefs head to New England for a Sunday night showdown this week."When you play a defense like that," Mahomes said, "you're not going to score a ton. The defense stepped up, made a lot of great plays and got us into great field position. I just went out there to maximize the game plan and score when I could."Indeed, it sure seemed as if the Kansas City defense played with a chip on its shoulder after hearing all season how bad it has been White Xavier Williams Jersey , and hearing all week how good the Jaguars would be.The Chiefs held on fourth down inside their 5-yard line early in the second quarter. They held again on fourth down late in the game. They strip-sacked Bortles, picked him off four times and returned one for a touchdown, all despite losing a handful of players to injuries and ejections .Chris Jones, who had the pick-6, was ejected after dropping an elbow on a Jacksonville lineman. Pass rusher Dee Ford followed him to the locker room a few minutes later after getting a second unsportsmanlike conduct penalty. Outside linebackers Justin Houston (hamstring) and Tanoh Kpassagnon (ankle) joined Eric Murray (lower leg) and fellow safety Armani Watts (groin) in getting banged-up.Yet a bunch of unheralded fill-ins responded quite well.Rookie pass rusher Breeland Speaks brought some pressure late in the game. Kpassagnon played well until he went down. And young safety Jordan Lucas, who was traded from Miami just before the start of the season, picked off his first pass after spending most of the season playing special teams."It's a team. We don't point fingers, any of that," Chiefs coach Andy Reid said. "We know that every week we expect every phase 鈥?offense, defense and special teams 鈥?to pick it up if the other phase is down. We've been able to do that so far."The result has been another 5-0 start, the Chiefs' third under Reid and second in a row. But while last year's team followed with six losses in a seven-game stretch, there are reasons to believe this year's team will follow a different path through the middle portion of the schedule."We learned a lot from what happened after our 5-0 start last year," Chiefs wide receiver Chris Conley said. "We know that we can't be excited about being 5-0. We have to be looking forward to the next game. We have to know that it's a long season and you have to build if you want to win."It helps that this year the Chiefs appear to be a more complete team."Last year we had a great team and we won a lot of games," Mahomes said. "This year we're just trying to learn from last year Youth Kareem Hunt Jersey , the little drought we had, and just try to make it a procession."NFL seasons are long," he said, "and there's going to be ups and downs. But you kind of just grind out every single day and try to get better, and you hope you can limit the downs and maximize the ups."
