for the Jaguars and their lack of success on the ground is a big part of that.The Jaguars led the league in rushing last season Dawuane Smoot Jerseys Stitched , but have dropped to 19th this year. Running back Leonard Fournette‘s difficulties have played a big role in that dip.Fournette missed six games with a hamstring injury, missed another due to a suspension and has gained just 396 yards on 115 carries while he’s in the lineup. He got just one carry in the second half of last Sunday’s loss to Washington and a comment he made to reporters on Thursday may explain why the team was looking elsewhere.“I could be in better shape,” Fournette said, via Jacksonville.com. “I’m fine, though.”Offensive coordinator Scott Milanovich said questions about Fournette’s condition were “for somebody else,” but the Jaguars are closing in on an entire season without a back rushing for 100 yards in a game and that’s not where they thought they’d be when they took Fournette fourth overall in 2017. Turning things around on that front will be essential to better days in 2019. Sick of seeing Jawaan Taylor mocked to the Jacksonville Jaguars? Getting irritated by ESPN mocking safeties on Day 2?

Getting irritated by ESPN mocking safeties on Day 2? Fair enough.Earlier this week, I spotlighted a handful of offensive players whom the Jaguars should consider if they make it to rookie free agency. In this edition, I focus on defense. The Jaguars have found some success in harvesting the undrafted rookie pool, an endeavor largely piloted by Senior Vice President of Football Technology & Analytics Tony Khan. Identifying high-upside athletes who stand a good chance of competing for roster spots has been a strength over the last few years, especially when it comes to the defensive side of the ball.Just last year Youth Dede Westbrook Jerseys , cornerbacks Quenton Meeks and Tre Herndon ended up making the final roster and look to be bigger contributors heading into their sophomore campaigns, and former UDFA safety Jarrod Wilson was re-signed to a solid contract to replace Tashaun Gipson as the starting free safety in 2019. So who should the Jaguars target?Defensive tackleKenny Bigelow, West VirginiaIf you are a hardcore college football fan who follows recruiting, Bigelow’s name may sound familiar.Along with Ole Miss’ Robert Nkemdiche, Kenny Bigelow was a coveted five-star recruit and played both defensive lineman and tight end positions in high school. Bigelow played his first five seasons at USC where he redshirted his freshman year in 2013 and then missed the 2014 and 2016 seasons with serious knee injuries that caused him to ponder retirement. Mostly a rotational nose tackle who saw limited playing time with the Trojans, Bigelow earned a sixth year of eligibility from the NCAA and grad transferred to West Virginia. In his 12 starts in 2018, Bigelow earned Second Team All-Big 12 honors and was runner up for Big 12 Defensive Newcomer of the Year.I mean, just look at his first snap against Tennessee this year:When studying Bigelow, I was astounded by the first step quickness and lower body explosiveness he has for a guy with two major injuries on the same knee. While his medical history would make a team like the Jaguars hesitant to burn a draft pick on him, his upside as a rookie free agent is certainly worth the risk. Bigelow put up 31 reps on the bench at his pro day and also ran a 5.09 forty yard dash for a nose tackle.Personally, I’m a huge fan of Temple DT Michael Dogbe, who I got to check out at East-West Shrine Game Dede Westbrook Jerseys Stitched , but it just doesn’t seem like Dogbe will go undrafted based on my understanding. Outside of Bigelow and Dogbe, Wyoming’s Youhanna Ghaifan, a talented three-technique who declared for the draft early, can be a bargain guy who may slip out of the seven rounds due to a suspension resulting from two misdemeanors stemming from an October altercation with a hotel employee. Ghaifan has draftable tape and is worth taking a flier on.Defensive endJarrell Owens, Oklahoma StateThe Jaguars certainly will be on the hunt for depth for both the strong side defensive end position behind Calais Campbell and weak side defensive end behind Yannick Ngakoue, so it’s likely they will be active in recruiting edge rushers in rookie free agency.Oklahoma State’s Jarrell Owens is a prospect that could vie for that strong side position. A two-sport athlete at Palestine High School in Texas who played running back and defensive end in addition to basketball, Owen was clocked running a 4.70 forty (some scouts I talked to had him at 4.60) and jumping a 39” vert at his pro day – at 265 pounds. Owens is durable and has never missed a game in his Oklahoma State career and shows a good blend of speed, power, and flexibility as a pass rusher when studying his tape. Other edge rushers that may be intriguing as a rookie free agents include Tennessee’s Kyle Phillips, North Carolina’s Malik Carney, Boston College’s Wyatt Ray and UCF’s Titus Davis. Phillips fits the strong side defensive end mold while Carney, Ray Youth Myles Jack Jerseys , and Davis could challenge for weak side edge rusher. LinebackerTy Summers, TCUSimilar to my crush on UAB wide receiver Xavier Ubosi last week, Ty Summers is the guy I have hearts written all over my notebook on defense.It’s easy to fall in love with Summers the athlete after his impressive showing at the Combine (9.69 RAS), but you really start to get enamored with the person as well when you do research into his background.Summers played as a dual-threat quarterback on offense and safety on defense at Reagan High School in Texas. Described a “weight room animal” and reportedly running the 40 yard dash in the 4.5 range as a freshman, Summers spent the summer of his senior year with his high school defensive coordinator to learn about linebacker reads upon learning he would be switching to inside linebacker at TCU. Summers would later finish with the second-most tackles in the Gary Patterson era. A team-first guy, Summers was asked to move to defensive end in 2018 and never complained despite it affecting his stock. Summers is a two-time Academic All-Big 12 selection and is active in the community off the field, finishing as a semifinalist for the Jason Witten Collegiate Man of the Year Award.You’re not missing anything, Evan. He’s good. It’s rare that you find a prospect who has played in all three levels on defense. Summers’ experience as a high school safety and quarterback makes him a tremendous processor in coverage as a potential WILL linebacker and his ability to blitz and rush the passer as a defensive end also makes him a great fit as a SAM linebacker for the Jaguars in addition to contributing on special teams.Hopefully a team doesn’t snatch Summers and his athletic profile on day three of the draft. Other fringe linebackers I like for depth for the Jaguars include Northern Illinois’ Sutton Smith (likely to be drafted), North Carolina’s Cole Holcomb, UTSA’s Josiah Tauaefa, and Oklahoma’s Curtis Bolton.CornerbackDuke Shelley, Kansas StateHe’s 5’9” Myles Jack Jerseys Stitched , weighs less than 180 pounds, and doesn’t have elite timed speed. What’s not to like, right?Shelley may not check all the physical and athletic boxes that you’d like from high-upside rookie free agents, but he plays the position like a lion and showed some of the best competitive toughness that I’ve seen in scouting for this draft class. The first true freshman to start at cornerback for Bill Snyder since 2006, Shelley has 31 career pass deflection in 38 career games as a boundary corner for the Wildcats and has returned 2 of his 8 career interceptions for touchdowns. More importantly, he’s dripping with swagger. Look at the ball flip at the end as he stares at the Baylor bench. In zone, Shelley is deliberate in his decision-making to pick up his assignments and even demonstrates some nuance and baiting ability to delay his breaks. Shelley is urgent in undercutting outs and flat routes and shows great enthusiasm and courage in run support despite being undersized. Shelley projects to be a scheme transcendent nickel cornerback due to his football intelligence, ball skills, playmaking ability, and short area quickness. With D.J. Hayden’s contract structured to be a likely release candidate after 2019, Shelley would provide ideal competition with Tre Herndon to take over at nickel for the Jaguars in 2020.If the Jaguars are looking for longer boundary corners to get in the mix with Meeks, a few prospects I like are Virginia’s Tim Harris Youth Yannick Ngakoue Jerseys , Texas’ Davante Davis, and Kentucky’s Chris Westry. SafetyVaughnte Dorsey, Texas TechThere’s a log jam of late round safeties in this draft and a much more prominent name like Miami’s Sheldrick Redwine or Temple’s Delvon Randall may be available once the dust settles, but I’ll go a little more under the radar with Texas Tech strong safety Vaughnte Dorsey. A JUCO transfer from Gulf Coast Community College, the former high school dual-threat quarterback is a stocky striker in run support who also excels in as a mental processor in zone coverage with plus ball skills. To illustrate his ability to contribute as a balanced safety in both coverage and run support, Dorsey finished second in the Big 12 in interceptions (4) in 2018 and also had 11 tackles in one game in a great showing against Oklahoma. Dorsey also adds a wrinkle as a blitzer and does a good job of timing the snap with great closing speed and pursuit angles to run down even the best athletes at quarterback (Kyler Murray). Dorsey is an ideal scheme fit as an interchangeable safety in the Jaguars 4-3 system and could challenge C.J. Reavis for a final roster spot.Other fringe safeties I’m high on include Troy’s Cedarius Rookard and West Virginia’s Toyous Avery.Which defensive UDFAs are you high on?
