The 2018 Chiefs rode their offense to a lot of success Travis Kelce Jersey , but they weren’t able to find a way past the Patriots in the AFC Championship Game.Defensive changes were central to the offseason moves made in hopes of taking the next step this year. Those moves were headlined by hiring defensive coordinator Steve Spagnuolo, trading for defensive end Frank Clark and signing safety Tyrann Mathieu as a free agent.Mathieu knows there’s a lot of excitement about seeing the new unit in action for the first time when they face the Jaguars on Sunday and said he’s taking it upon himself to make sure the team keeps everything in balance.“It’ll be the first time really playing with my group and playing with my guys in a live game — in a game that counts,” Mathieu said, via the team’s website. “It’s going to be a lot of different emotions, up and down. I think it’s my job to manage the group and make sure everybody’s focused on the next play. Just going out there with a lot of swagger and a lot of intensity. A lot of people here haven’t necessarily seen me play in a Chiefs uniform, so it’ll be important for me to go out there and get off to a fast start.”The Chiefs offense led the league in points scored and yards last season and it’s expected to be a top unit again this year. If the defense can take a few steps forward Tyreek Hill Jersey , the Chiefs should be in the thick of the hunt for a title this year. The Kansas City Chiefs made a roster move on Tuesday, adding defensive back/strong safety Chris Cooper to the practice squad.Cooper, 24, first entered the league in 2018 as an undrafted free agent with the Indianapolis Colts but was waived by the team with an injury designation prior to the 53-man roster deadline.Cooper spent a couple weeks on the Cincinnati Bengals practice squad before being released last week and landing with the Chiefs on Tuesday.The 5-foot-10, 202-pound Cooper spent three years at Stony Brook University (2015-17), where he compiled 147 tackles Carlos Hyde Jersey , five pass breakups and four interceptions. According to Josh Thomson of lohud.com, Cooper began garnering NFL attention his senior season, when he recorded nine tackles away at South Florida. He then ran a 4.43-second 40-yard dash at the Stony Brook pro day. For comparison’s sake, that is the same speed Sammy Watkins ran the drill at his Scouting Combine.There is no surprise there was interest from the Chiefs, who made a change late in the season to play cornerback Charvarius Ward stemming from his speed.Cooper also told lohud he talked to 16 teams prior to the draft, took calls during the sixth and seventh rounds and received contract offers from the Seahawks Juan Thornhill white jersey , Redskins and Colts.Cooper likely won’t be on a 53-man roster on Saturday, but he will be a member of the organization playing the Colts in the divisional round, coming full circle his rookie season.
