on Sunday Trevor Siemian was never asked to do anything too risky in 2016 and the Denver Broncos offense finished with the most three and outs Youth Royce Freeman Jersey , but Siemian had 3400 yards with an 18-10 touchdown to interception ratio. That conservative mentality changed in 2017 and more pressure was put on Siemian, Brock Osweiler, and Paxton Lynch who all then became a turnover machines. The Broncos didn’t lead the league in three and outs, but the turnovers were leading to blowout losses.That is the delicate balancing act new Broncos starter Case Keenum must follow heading into this season. You can’t win games if you don’t score points and you can’t score points in the NFL if you don’t take some risks. Keenum seems to understand that. He noted the importance of taking care of the football, but also the need for points in this league.“It’s different every week depending on the gameplan and depending on what the points of emphasis are from V.J. (Vance Joseph) and Billy (Bill Musgrave) and those guys,” Keenum said of game planning. “Obviously, taking care of the football and staying on the field. Getting first downs and getting touchdowns. You’ve got to score points in this league to win and you’ve got to take care of the football, especially against a team like Seattle.”The best way a quarterback can be successful is to have a strong rushing attack behind him. That is one area the Broncos seemed to have gotten a heck of a lot better at in just a single draft with the addition of third-round pick Royce Freeman and undrafted rookie Phillip Lindsay.Freeman has already been named the starter and there is near universal praise for what Lindsay is going to be able to do to opposing defenses in space.“We’ve got coaches coming up with a great gameplan as far as running and passing,” Keenum said. “They’ve always, historically, been a really good defense against the run—very stingy. They like to play a lot of guys down low and stop the run. They do a good job getting in their spots that they drop to or if they play man. Zone or man, they are good at covering the pass. It’s going to be tough. We have to establish the run and be able to throw the ball too.”How the Broncos rushing attack performs in Week 1 will go a long way in determining how successful this offense will be this season. Keenum sees it that way too, because picking up a first down on a third and two is a lot different than trying to do it from a third and eight. Jacksonville coach Doug Marrone has seen enough in five games of Chiefs quarterback Patrick Mahomes to compare him to some of the best to ever play the position.Or more accurately Cheap Derek Wolfe Jersey , an amalgamation of the best to ever play it.Think the arm strength of Brett Favre and the accuracy of Tom Brady. The poise of Aaron Rodgers, the gritty gamesmanship of Ben Roethlisberger and the intelligence of Peyton Manning."You are talking," Marrone said, "about someone that is a combination of a lot of the greatest players that have ever played that position with the way he is playing."Now, the question is whether the NFL's best defense can slow him down.The Jaguars (3-1) head to Arrowhead Stadium on Sunday to face Mahomes and the Chiefs' high-flying offense in what is arguably the game of the week . Jacksonville's only loss came by a field goal to the Titans, while the Chiefs (4-0) are coming off a dramatic fourth-quarter comeback win in Denver.And whereas the Jaguars are allowing a paltry 259 yards per game, and top the league in scoring defense, the Chiefs are putting up 410 yards and an NFL-best 36 points per game.Much of that is due to Mahomes , who is averaging close to 300 yards passing. He has already thrown 14 touchdown passes without an interception, and his ability to make plays when everything breaks down — like that audacious left-handed pass against the Broncos — has turned him into an early MVP front-runner."He gives you challenges every which way," Marrone said, "whether you put him in the pocket (or not). He can make every throw. He makes quick decisions. You get him out of the pocket and he can extend plays. He is athletic enough to run and run for a long way and take it to the house. He has great command, and he has great weapons around him and an outstanding offensive line."Right now Youth Garett Bolles Jersey , offensively, what you're seeing is that it's kind of unbelievable," Marrone said, "which is going to be a great challenge. We have our hands full."To the Jaguars' credit, the Chiefs are saying the same thing about them.Their defensive front is anchored by Calais Campbell and allows fewer than 100 yards rushing per game. Telvin Smith is one of the game's top linebackers. And the defensive backfield is led by cornerbacks Jalen Ramsey and A.J. Bouye, who have made life miserable for quarterbacks all year."This is by far the best defense we'll have faced ," Chiefs wide receiver Tyreek Hill said, "but I'm always up for a challenge. The best always go against the best, so we'll be ready."As the Jaguars prepare to visit the Chiefs, here are five dominant story lines:SIDELINED STARSThe Jaguars will be without running back Leonard Fournette , who is again sidelined by a lingering hamstring injury, and backup cornerback D.J. Hayden. The Chiefs remain without star safety Eric Berry, who has been "day to day" for about two months with a troublesome heel.WINNING STREAKSThe Chiefs have won nine straight regular-season games dating to last season Youth Phillip Lindsay Jersey , but the Jaguars have found it far more difficult to string together victories. The Jaguars never won more than three in a row last season."It's something we've struggled a bit with," Jaguars quarterback Blake Bortles said. "This is the perfect opportunity to kind of break that mold of going up and down back-to-back weeks, playing good and then following it up with a poor performance."HENNE'S HELPThe Chiefs could have an advantage in backup QB Chad Henne, who started 53 games over six seasons in Jacksonville. He also appeared in two games in mop-up duty last year, and gives Kansas City the ability to diagnose and understand the Jaguars' offense.RUN AWAREThe Chiefs finally got running back Kareem Hunt going last week against Denver, and last year's NFL rushing champion responded with his first 100-yard game this season.It was a good reminder for the Jaguars that they can't focus entirely on Mahomes and the Chiefs' pass offense."You would think that, but that's not the case. I'm being honest," Marrone said. "We understand the running backs. We understand how good the line is. We obviously know the weapons on the outside. We obviously know that the field will be stretched. We're going to have to play well. It will be a challenge ."ARROWHEAD MYSTIQUEThe party-like atmosphere that was prevalent in Kansas City throughout the 1990s has returned with the success of Mahomes and Co., and Marrone is keenly aware of it."It is going to be so damn loud," he said. "We will all have to be on the same page. I don't think a lot of people will be able to hear a lot of things when you go that. That is probably one thing about Kansas City: It is probably the loudest place I have ever been."
