for some running back depth and reportedly already signed David Williams off the Denver Broncos practice squad. According to Ian Rapoport of NFL Network Jaelen Strong Jersey , the team is also working out former Broncos and Kansas City Chiefs running back Jamaal Charles on Tuesday.Charles played in 14 games last season for the Broncos as a backup, rushing the ball 69 times for 296 yards and a touchdown, also catching 23 passes out of the backfield for 129 yards.The 32-year old running back best days are behind him Tanner Lee Color Rush Jersey , but in lieu of making a trade for a veteran perhaps the Jaguars are kicking the tires to see if he still has enough left in the tank to play a part-time role in the Jaguars offense while TJ Yeldon and Leonard Fournette are still banged up.Personally, Iíd look at some of the 1-4 teams who are all but out of it and see if any backs with expiring contracts can be pried away for a Day 3 pick. The Jacksonville Jaguars open as a three point favorite on the road as they travel to take on the Dallas Cowboys late Sunday afternoon. Some people may be surprised after losing 30-14 to the Kansas City Chiefs to see the Jaguars as favorites on the road, but the reality is the Cowboys just arenít very good right now.If the Jaguars offense can rebound from their disastrous showing against a solid Cowboys defense , they should be able to control the game. The Cowboys offense has struggled to do much other than occasionally run the football well so far in the 2018 season. Dallas averages just about 17 points per game and the Jaguars, even after Sunday, average allowing 17.2 points per game.The big advantage for the Jaguars should be the fact that the Cowboys passing game has been all but nonexistent. Dak Prescott has struggled passing the ball so far this season Calais Campbell Jersey , throwing just five touchdowns and being sacked 16 times. The teamís leading receiver is actually running back Ezekiel Elliott, as Dallas doesnít really have any big threat at the receiver or tight end positions.The big key will be if the Jaguars offense, more specifically Blake Bortles A.J. Bouye Color Rush Jersey , can rebound from their poor showing against the Chiefs. Weíll also need to keep an eye on the left tackle position as well, since Josh Wells picked up a groin injury and Josh Walker may need to fill in.
