s impressive play in Sean Lee’s absence In a weekend that saw the Philadelphia Eagles Youth Kavon Frazier Jersey , Washington Redskins, and New York Giants all fall, the Dallas Cowboys were unable to take advantage and stake their claim in the NFC East. Fortunately, their 2-3 record will not keep them out of the hunt, but it was certainly a missed opportunity that leaves a bad taste in the mouths of Cowboys fans.The offense struggled to get into the end zone, which is already a common theme through five games this season. The defense, meanwhile, allowed Deshaun Watson, DeAndre Hopkins, and company move down the field, only to stiffen up in the red zone. While the defense did not play exceptionally well all night, they certainly appeared to have played well enough for a win.Let’s take a look at how the rookies performed on the big stage on Sunday Night Football in week five.Leighton Vander EschLeighton Vander Esch has seemingly been playing with a chip on his shoulder since taking the field for the Dallas Cowboys in his first season. Maybe it is because he remembers the fan reaction when Dallas selected him in AT&T Stadium. Maybe it is because he wants to prove that a former eight-man football player can not only play — but succeed — on the highest level. Maybe he is just good at football?Whatever the case is, LVE has been playing at an exeptional level for this defense since week two http://www.cowboysauthorizedshops.com/authentic-anthony-brown-jersey , where he played approximately 20 snaps and made seven stops. Vander Esch followed that up with impressive outings in a loss versus the Seahawks in Seattle and again in a victory over the Lions back at home in week four.The talk has been surrounding Jaylon Smith — who had himself a solid game in his own right as he flew all over the field — but Vander Esch did not disappoint against Houston, either. The Boise State Broncos product led the team in tackles with 11 during the Sunday Night Football overtime loss, nine of which were solo. Whatever your feeling was when the Cowboys selected him back in May, Vander Esch appears to be a stud at linebacker for America’s Team.Connor WIlliamsSome Cowboys fans were more thrilled about the Connor WIlliams pick than the LVE pick, as the Texas Longhorns product had some first-round hype with his ability to play different positions across the offensive line. With the hole at left guard, Williams would seemingly be an ideal fit next to Tyron Smith and Travis Frederick.While Frederick has yet to play a regular season snap in 2018, Williams has had to hold his own against quality defensive fronts over the course of his first month on the professional level. Williams had his ups and his downs, allowing sacks and QB pressures, but also beinga solid blocker for Ezekiel Elliott in the run game.Williams was called for a critical (and controversial) holding call on big Zeke run that looked to give Dallas some momentum on Sunday evening. It was a call that hurt the Cowboys offense from gaining traction in an eventual loss.Michael GallupThe need for playmakers, other than Zeke, on the Cowboys offense is evident. Dak has struggled, the play-calling has raised eyebrows, and the offensive line has struggled without Frederick manning the middle. There was a lot of hype surrounding the team’s third-round selection http://www.thecowboysfootballauthentic.com/chris-jones-jersey-authentic , but Gallup has yet to really make an impact with the Cowboys through five games this season. He drew some PI’s in week one and made that 37-yard grab in week four, but other than that?Gallup grabbed one pass for six yards — but, in fairness, the rookie may have had a little more to his total on this play, had things gone right:Whether it be the quarterback, the receivers, or the coaching staff (or all three), this passing game simply cannot get going. Will Gallup be able to make an impact before season’s end?Dorance Armstrong Jr.Dorance Armstrong Jr. is behind a loaded defensive end unit in Dallas, but the Kansas Jayhawks rookie has shown some potential with the snaps that he has received over his first five games with the Cowboys. Armstrong was able to find his way into the box score during his limited snaps, making one stop on the night. The rookie also saw some snaps at the 3-tech during the game on passing downs. It will be interesting to see how the staff uses the 6-foot-4, 257-pound defensive lineman moving forward.Jerry Jones: Cowboys haven’t had a “true No. 1” receiver for several years The Dallas Cowboys are struggling in the wide receiver department this season. Not only are they failing to have success themselves, but part of the reason they just lost to the Houston Texans is because of a superstar wideout in DeAndre Hopkins.It’s one thing to know something, but it’s another to have it rubbed in your face. Maybe that’s what happened to Jerry Jones because he’s been awfully cavalier with his comments about a “number one” receiver in the fallout of the loss.The leading receiver on the Cowboys for almost the last decade has been Dez Bryant. Obviously Dez was released by the team this past offseason Womens Terrance Williams Jersey , but that was less than a year ago which makes Jerry’s comments on 105.3 The Fan Tuesday morning interesting. He noted that it had been “several years” since the Cowboys had a true top threat.When Jones made his comments about not having one in general immediately following Sunday’s loss, they naturally stirred up questions:Why didn’t you get a No. 1 receiver then?Why did you only sign the players that you did?Why didn’t you draft someone who could be that player?As always in situations like this, the questions aren’t all necessarily rational, but they happen in times like these. We weren’t the only one making remarks though, Dez Bryant made yet another plea to re-join the team that released him six months ago by inferring that he could be the player Jones is looking for.A few things seem clear at this point:The Cowboys don’t have a “No. 1” receiverThey haven’t had one in some timeConsidering Dez Bryant was on the team as recently as last season, the Cowboys didn’t view him as a “No. 1” receiver and therefore don’t right now when needing one desperatelyDez Bryant was a fantastic wide receiver across the whole of his career with the Cowboys, but is it really fair to say that he was a “No. 1” receiver over the last few seasons? Of course not.What Dez did in 2016 was generally underrated as far as things go, and to his credit he dealt with his own injury and a quarterback change; however, the point remains that Dez never re-gained the form he had from 2012-2014 after he signed his contract extension in 2015.That’s about it.
