I'm gonna dress this one up a little bit and try to make the reading a little easier. I think the Cowboys are going to find that they will be deeper into a rebuild than even they planned for. The offensive and defensive lines both need work. The offensive line is showing weakness, and will inevitably be adjusting to new blocking schemes under McCarthy. New blood and beef will be needed fast if the Cowboys want to count on having Ezekiel Elliot's big contract pay dividends. The defensive line needs beef and depth. With running backs like Saquan Barkely, Derrick Henry, and our own Ezekiel Elliott, teams cannot rely on smaller, faster linemen and speedy linebackers to stand up to the pounding an offense committed to the run can dish out. While McCarthy has used great players such as Clay Matthews at linebacker, he is not one to allow his defensive line to be pushed around. With Sean Lee likely retiring and Jaylon Smith not completely dependable at linebacker, this group will need work, too. Stephen Jones is a proponent of using younger guys in the secondary rather than keeping higher paid veterans because of the NFL's agreement with the players that allow for them to be paid less. This has been a staple of the Cowboys salary cap management for years. Don't look for that to change, as the Cowboys seem focused on offensive contracts in the offseason and a total of 23 unrestricted free agents. Kai Forbath was a late addition, and while he looked good in limited opportunities, the Cowboys are nowhere near set at the kicker position. There will inevitably have to be a competition for the job. The situation with Dak Prescott has the Cowboys in a pickle. Prescott's play hasn't justified the top money he is wanting, and with his contract expired he will likely receive the non-exclusive tag. And teams like Tampa Bay might very well jump at the opportunity to sign him. Jamis Winston is pretty much in the same situation, having failed to show that he is the guy in Tampa. Indianapolis is likely looking, too. No one expects Dak to leave Dallas, but contract issues still make this a possibility. I think the Cowboys MUST go after Case Keenum or Marcus Mariota and solidify the quarterback position. Then they can deal with whatever issues Dak's contract creates with security at the position. The Cowboys have a need for a burner at receiver that can change the game and dictate coverages that open up the game for the rest of the Cowboys receivers. Jarwin appears to be the best young tight end, but the Cowboys will need depth and will likely add a couple to the mix. How McCarthy approaches the run game will likely mean changes in personnel. I look for him to add a receiver/running back that can throw defenses off their game. I think the Cowboys have their hands full for this off season, as the new schemes and philosophy of McCarthy's vision for the team inevitably create changes. It will be interesting to see how in depth these changes affect the team, and McCarthy will want to remain competitive: Because the NFL will most assuredly not miss the opportunity for a ratings bump by scheduling the Cowboys vs the Packers early in the season on a Sunday night.
