What three weeks ago was a promising season that appeared to be barreling towards a second-consecutive playoff appearance and vying for another AFC South title www.authenticsjacksonvillejaguars.com , has officially gone fully off the rails, following a complete ass kicking for the second consecutive week on the road, this time at the hands of what was supposed to be a feckless Dallas Cowboys team by a score of 40-7.The Jacksonville Jaguars offense led by the consistently inconsistent Blake Bortles could never get anything generated, and for another week committed more turnovers than the defense could make up for as Bortle threw one God awful throw into triple coverage for a near pick six, and receiver Keelan Cole fumbled while attempting to turn and run on a reception in the second half. The offensive line wasn’t near the problem it was a week ago in Kansas City, but Bortles never looked comfortable and the Jaguars once again inexplicably appeared to veer away from the running game when T.J. Yeldon was performing well when given the opportunity.The biggest takeaway this week (and the most disheartening) is the play of the defense over the past two weeks. The much-heralded defensive line, while hurrying Dak Prescott at times, had little to no pressure applied when the game was still on the line and it is now a more consistent trend than an aberration this season for the “Sacksonville” defense Jacksonville Jaguars T-Shirt , to be anything but and a team that three weeks ago had allowed only four touchdowns all season, has allowed a combine 70 points in two weeks.In the back end, defensive coordinator Todd Wash’s insistence on running a zone coverage scheme forcing his corners to play off, continues to allow receivers to run rough shod through the once feared secondary. With safety Barry Church and corners A.J. Bouye and Tyler Patmon seeming to consistently have the most issues with making plays within the scheme.Something has to change quickly for this team and the answer is almost certainly not just the return of Leonard Fournette, whenever that is. If there is a saving grace, the rest of the AFC South is abysmal as well, with Tennessee and Indianapolis losing again today, and now a three-way tie in the standings at 3-3 between the Jaguars Jacksonville Jaguars Hats , Tennessee Titans, and Houston Texans (who held off the Buffalo Bills this afternoon) and have won three straight heading into what is now a must-win game for the Jaguars next Sunday in Jacksonville. Jaguars running back T.J. Yeldon hasn't started a game in nearly two years, a frustrating stretch that forced him to work harder and be more patient.He always felt like he would get another shot. He didn't expect it to be this week.But with Leonard Fournette missing practice because of a strained right hamstring, Yeldon is getting the majority of practice repetitions and preparing to carry the load Sunday against the New England Patriots (1-0)."Whenever my number is called, I'll always be ready to get into a rhythm and go," Yeldon said. "I really don't have a problem with that."While many outsiders believe there's a huge drop-off from Fournette to Yeldon, the Jaguars (1-0) insist there's only a marginal difference between the two. It's a big reason the old-school, run-first team kept only three running backs 鈥?Fournette Jacksonville Jaguars Hoodie , Yeldon and change-of-pace speedster Corey Grant 鈥?on the 53-man roster.Fournette tweaked his hamstring in the first half of Jacksonville's season opener at the New York Giants . He sat out practice Wednesday, and coach Doug Marrone said the plan is for him to do the same Thursday.Marrone said Fournette will go through tests Friday to see whether he's able to play in a rematch of the AFC championship game.Jacksonville is likely to be cautious with Fournette, the centerpiece of the team's offense. The fourth overall pick in the 2017 NFL draft, Fournette ran for 1,040 yards and nine touchdowns last season. He also caught 36 passes for 302 yards and a score.Fournette ran nine times for 41 yards against the Giants. Yeldon had 51 yards on 14 carries and caught three passes for 18 yards, including a 4-yard touchdown late in the second quarter.Marrone praised Yeldon for the strides he's made."He has always been good," Marrone said. "I think he is more explosive. He's stronger. He's elusive. I think he can carry a load of carries. I just think he has done a nice job. I really do."Yeldon has reason to take advantage of his opportunities. A second-round pick from Alabama in 2015, Yeldon is in the final year of his $5.9 million rookie contract.Jacksonville is prepared to lose Yeldon in 2019 free agency Youth Customized Jacksonville Jaguars Jerseys , believing another team will be able to offer him a starting job or at least more carries.Yeldon said he's "not too much worried about that," adding "it'll play itself out." But he's clearly planning for the future. He dropped weight in the offseason, getting below 220 pounds for the first time since his college days, and hopes to show he's a three-down back."I feel better, lighter, quicker, faster, more explosive www.jaguarsauthorizedshops.com ," he said. "I feel like it makes a big difference. I can cut better. I'm doing a lot of things better. I feel more comfortable this way."The Jaguars hope it shows on the field. With Fournette uncertain to play, Yeldon could end up in a featured role.It's a spot he didn't expect. It's also a position coaches and teammates say he can handle and prove to doubters there's not much of a dip from Fournette."That's their fault," receiver Keelan Cole said. "That's on them. If they want to think that, just tell them to tune into the game."
