There isn't much that's familiar on Sunday when it comes to the Jaguars offense trying to move the ball against the Chiefs defense. Almost everything about the two units has changed.
When it comes to the Jaguars offense against the Kansas City Chiefs defense on Sunday at TIAA Bank Field, it's almost as if the game the two teams played at Arrowhead stadium last season didn't happen.
Both units, regarded as each team's weakness after the 2018 season concluded, were revamped, and both teams hired new coordinators -- John DeFilippo for the Jaguars' offense and Steve Spagnuolo for the Chiefs' defense.
Through the draft and free agency, the teams attacked those weaknesses. Schemes underwent wholesale changes.
As a result, who knows what to expect on Sunday?
Only three players who started for the Jaguars in that 30-14 loss to the Chiefs on Oct. 7, 2018 will be starting on Sunday, all on the interior offensive line: center Brandon Linder and guards Andrew Norwell and A.J. Cann.
Kansas City's defense will have only four starters on Sunday who played against the Jaguars last season, defensive tackle Derrick Nnadi, defensive end Chris Jones, linebacker Anthony Hitchens and cornerback Kendall Fuller.
The Jaguars have re-tooled their offense to match the strengths of free-agent signee Nick Foles and the philosophy of DeFilippo, Foles' former quarterback coach with the Philadelphia Eagles. The tight ends and running back Leonard Fournette will be emphasized more in the passing game, the run-pass options with former quarterback Blake Bortles is out the window and wide receivers will be used more creatively.
At least that's the word after six weeks of training camp. Except the first unit played only one quarter in one preseason game and the offense put only three touchdowns on the board, two by third-team quarterback Alex McGough, who was cut.
The Chiefs have moved to 4-3 look on defense after playing a 3-4. The key addition was end Frank Clark in a trade with Seattle, and unrestricted free agents signees Tyrann Matheiu at strong safety, Alex Okafor to bookend Clark on the other side of the line, Damien Wilson at linebacker and Bashaud Breeland at corner.
Here's where the Jaguars might face some tough matchups: Clark, who had 13 sacks last season and Okafor, who started all 16 games for New Orleans and had four sacks, will be going against Jawaan Taylor at right tackle, a rookie, and Will Richardson at left tackle, who will move over from right guard to fill in for Cam Robinson and Cedric Ogbuehi, who are both injured.
There's also the Honey Badger factor when facing Mathieu. He likely will be playing a hybrid strong safety/linebacker spot and the Chiefs will obviously try to take advantage of his knack for big plays. In three career games against the Jaguars, Mathieu has 13 solo tackles, two interceptions and four passes defensed.
DeFilippo, who has coached against Spagnuolo when both were in the NFC East, said he expects almost anything.
"We have our hands full," he said. "He likes to blitz, he likes to bring a lot of pressure and we're going to have to do a good job of calming the storm early."
The opposite happened last season in Kansas City. Bortles was personally responsible for five turnovers, and Jones took an interception for a touchdown in the second quarter. Bortles also was sacked twice and had three of his turnovers in the first half as the Chiefs took a 20-0 lead.
The good news is that Foles gets the ball out quickly, with accuracy and hasn't been nearly as prone to turnovers as Bortles. If he can get wide receivers Dede Westbrook, Marqise Lee, Chris Conley and D.J. Chark in one-on-one matchups when the Chiefs bring pressure, the Jags can break some big plays.
"They're going to mix it up with coverages," Foles said. "They're going to blitz some. They'll have something dialed up for us."
The Chiefs also use a nickel frequently, with Wilson and Hitchens at linebacker. But the Jaguars might be able to pop some runs with Fournette early, especially of Foles is able to beat pressure and get the ball out, forcing the Chiefs to back off.
Another issue is whether the Jaguars might try to play ball control early to try and limit possessions for the lethal Kansas City offense and quarterback Patrick Mahomes.
Foles said that will depend on the situation at the time.
"We're going to play our game," he said. "What that means is the play's going to be called, we're going to focus on that play and we're going to work on doing our job on that play ... in that moment and that's all we can do."
