Everybody knows about the struggles concerning the Dallas Cowboys offense. The passing game cannot get going Youth Sean Lee Jersey , the play-calling has drawn criticism, and even the workhorse, Ezekiel Elliott, made some crucial mistakes last week. As a result, the Cowboys sit at 1-2 prior to an important matchup with the Detroit Lions.Change needs to happen within the offense if this season is going to get on the right track. Jason Garrett already shut down any rumors of removing Scott Linehan from play-calling duties and Dak Prescott is still going to be behind center.With that said, is there any chance that Dallas is interested in making a move to improve the personnel on the offensive side of the ball, either by a trade or free agency? If so, an intriguing option at wide receiver appears to be available in now-former Titans receiver Rishard Matthews.Matthews, 28, is in his seventh season in the NFL, spending the first four years of his career with the Miami Dolphins before suiting up with the Titans for the past three. The Nevada product had one decent season down in South Beach before moving to the Music City.With the Titans, Matthews put together two solid seasons in 2016 and 2017, averaging 59 catches, 870 yards, and nearly seven touchdowns over the course of those two seasons. Through three games in 2018 Color Rush Byron Jones Jersey , the veteran wideout has yet to start a game, making three grabs for a grand total of 11 yards.Matthews, according to Rapoport, requested a release from the team after signing a one-year, $7.75 million extension with the team just a few weeks ago. Should the Cowboys have any interest in bringing in a new face in?On one side, the Cowboys have already tried bringing in some new faces in an effort to overhaul the receivers position. Allen Hurns was the marquee name, but Hurns has yet to make an impact through three games. Deonte Thompson was brought in to add some speed to the room, but he has only recorded 83 yards in three games. Then, there is Michael Gallup, the third-round rookie who — like most first-year receivers — is having to adjust to the NFL game.On the other side, the Cowboys can do much worse than attempt to bring in Matthews in an effort to give this offense a breath of fresh air. The 6-foot, 217-pound target was Marcus Mariota’s go-to perimeter threat during his time with Tennessee, but the team selected Corey Davis in the first-round in the 2017 draft. The Cowboys, though, seemingly have a need for a receiver to step up on the outside to relieve some pressure for Ezekiel Elliott Color Rush Chidobe Awuzie Jersey , as well as free things up for Prescott.Dallas did bring back Brice Butler last week, which was a surprising move to many. Prescott appeared to have a connection with Butler, especially on the deep-ball and on plays that broke down; but can Butler be a reliable receiver? If this team is serious about getting the passing game on track, looking hard into signing Matthews would be a smart move. The wideout appears to be recovered from a torn meniscus that he suffered over the offseason, and he has the talent to at least be an upgrade in the receivers room, should the Cowboys go in that direction.Cowboys vs. Panthers: Five things to watch in the game The Dallas Cowboys will be playing football on Sunday in a real game that will count in the standings. Can you believe it? The time has finally arrived. The Cowboys will square off with their first NFC South team as they travel to Carolina to face the Panthers. The last time these teams met was in 2015 and the Panthers gave the Cowboys a 33-14 Thanksgiving beat-down. Carolina came into that game 10-0 and finished 15-1 en route to a Super Bowl appearance.The Cowboys are hoping for different results this time as they look to get off to a good start in 2018. It’s should be a great game as these teams are evenly matched, but what are some things that could be the difference maker? Here are five things to watch when these two teams square off.Panthers DT’s vs. Cowboys interior OLThe Cowboys were going to have their hands full with the Panthers stud defensive tackles Dontari Poe and Kawaan Short no matter what, but the absence of All Pro center Travis Frederick is going to make it that much more challenging. Backup center Joe Looney has been solid in relief, but when you consider that he’ll have rookie Connor Williams on his left, that can create a cause for concern for Cowboys fans as they fend off two former Pro Bowlers.The offensive line is such an important part of the Cowboys success. They need it working to get Ezekiel Elliott going and they need it to keep Dak Prescott upright. Winning the battle in the trenches is going to be key for Dallas on Sunday.Which will effectively influence...Cowboys first-down efficiencyThere is no secret that the Cowboys are going to employ a heavy does of the running game. Keeping quarterback Dak Prescott in manageable down-and-distance situations is going to be imperative and the Cowboys offense will need to win on early downs to make that possible. With the tough defensive front of Carolina, it’s going to be difficult for the Cowboys to move the pile. Dallas will need to work in some bootleg tosses, play-action, and quick passes in order to keep the Panthers from overloading against the run.If the Cowboys get stuffed early or have some negative plays that put them behind the chains, then their offense could be forced to play uphill. It’s going to be important for the Cowboys to be efficient on first down.Randy Gregory vs. Taylor MotonThe Panthers offensive line is beat up as several key starters are battling injuries. One of those key starters is left tackle Matt Kalil who was selected fourth overall in the 2012 NFL Draft (by Minnesota). On Tuesday, the Panthers put Kalil on injured reserve Color Rush Joe Looney Jersey , making him unavailable to them for the first half of the season.That leaves second-year tackle Taylor Moton to protect Cam Newton’s blindside. While Panthers fans are pleased with the progress of last year’s second-round pick, Moton is very inexperienced and only played five snaps last year.Opposing Moton will be another second-round pick who doesn’t have a whole lot of playing experience himself - Randy Gregory. However, the Cowboys young edge rusher has hit the ground running once he was reinstated by the league and he’s ready to show the world what he can do. This will be an interesting battle to keep an eye on as how well these players perform will have a huge affect on how successful these teams can be this season.Double-down on double-deuceChristian McCaffrey can be explosive when he gets in space and the Cowboys defense will need watch this guy carefully. McCaffrey can beat you as a running back, but he’s even more dangerous catching passes as the majority of his 1,000+ scrimmage yards last season came as a receiver. With Panthers coach Ron Rivera indicating that McCaffrey will get a heavy amount of touches, this could open things up for the second-year running back to have a big season.The Cowboys will counter that with the great explosiveness of All-Pro linebacker Sean Lee. And with the improved movement from Jaylon Smith, the defense has a good core group of players who can go after the ball carrier. When it comes to McCaffrey, the Cowboys better allocate an extra defender to track his whereabouts. He’s a slippery littler sucker and if they don’t have an insurance policy in place when one guy misses, it could turn into a big play for Carolina.The rookie receiversThe Cowboys didn’t select fan-favorite D.J. Moore in the first round, but the Panthers did. Dallas opted to wait until the third round to draft their new wide receiver when they selected Michael Gallup with the 81st overall pick. How well will these young receivers fan in their NFL debut?Devin Funchess is the Panthers top receiving threat at the moment, but with with the talent of Moore, it’s only a matter of time before he starts becoming more involved in the offense. Cam Newton has a big arm and if Moore gets loose deep down field, it could result in a big play for the Panthers offense.The Cowboys have an assortment of receivers and could end up dressing all six of them on the roster. It’s unclear what Gallup’s role will be, but he developed some nice chemistry with Prescott in training camp. Can the rookie makes a splash in his first NFL game?What will you be watching on Sunday?
