After looking through the possible targets, expert projections and going around the rumor mill, here's one last mock draft. The Cowboys will focus this draft on fixing up their defensive unit while adding a few key pieces for the offense. Here's a look at the last seven-round mock draft for Dallas before Day 1 kicks off.
Round 1, Pick No. 16: Timmy Jernigan
Outside of a move to trade up, the Cowboys won't be able to land top defensive tackle Aaron Donald. For the purpose of this mock draft, possible trades were not taken into consideration.
At pick No. 16, the Cowboys should focus their attention to finding Melton a top-notch partner to rush the QB with. Having two young, talented tackles on the defensive line is exactly what Dallas needs.
Round 2, Pick No. 47: Terrence Brooks
The next step for rebuilding the defense has to be addressing the safety position. Terrence Brooks has the skills to be an instant starter next to Barry Church. He has an impressive 5'11", 198-pound frame that allows him to race towards the ball-carrier. Brooks ran a 4.42 40-yard dash at this year's NFL combine.
As for his coverage skills, being a former cornerback, Brooks knows all about getting between the ball and the defender. The Florida State product can help the Cowboys at both positions and no matter where he lines up, can provide stout coverage.
Round 3, Pick No. 78: Jackson Jeffcoat
His father Jeff was a solid starter for the Cowboys and Jackson Jeffcoat will continue the family tradition. At 6'3", 247 pounds, Jeffcoat has the power to match up with plenty of blockers he'll face at defensive end. His speed is another advantage that he'll have over most offensive linemen.
At the NFL combine, Jeffcoat ran a 4.61 40-yard dash time, showing off that quickness that helped him get to so many QBs in college. Dallas will be all smiles if it can land Jeffcoat in the third round and put its immediate defensive line needs to rest.
Round 4, Pick No. 119: A.J. McCarron
Romo is 34 years old and has had two back surgeries in as many offseasons. Dallas doesn't need to draft someone to replace him just yet, but it's time to find his heir. McCarron comes from a pro-style system and has mechanics as good as any QB in the draft.
The Alabama product knows how to throw the deep ball and gets rid of the ball quickly and decisively. McCarron has all the talent a team could hope for out of quarterback taken in the fourth round. In this draft with plenty of promising players at this position, Dallas has to take someone to fill Romo's shoes for when he retires.
Round 5, Pick No. 158: David Yankey
After addressing all their big needs, the Cowboys need to get some depth at the guard position. At 6'6", 315 pounds, Yankey has that size Dallas has always loved for its offensive linemen. He knows how to use that frame to blast through defenders and make room for his running back. With a little coaching up, Yankey could become a solid starter.
Round 7, Pick No. 229: Terrance Mitchell
With their first of six picks in the final round, cornerback is as good a position as any to address. Oregon product Terrance Mitchell has some great acceleration and would provide some needed depth at the position. It would make perfect sense for Dallas to grab a corner in the final round considering Morris Claiborne's struggles in 2013 and the lack of depth at the position.
Round 7, Pick No. 231: David Fluellen
After letting Phillip Tanner walk in free agency, there's room for Dallas to bring in a running back. Joseph Randle was drafted just last year, but providing him and Lance Dunbar some competition would be a smart move.
Round 7, Pick No. 238: Mike Davis
Even though Cole Beasley had some solid moments last year at wide receiver, the Cowboys need to bring in another young player at the position. With Miles Austin gone and Dwayne Harris on punt and kick return duty, Dallas could use some insurance at wideout. Davis is a homegrown talent that the 'Boys won't be able to resist.
Round 7, Pick No. 248: Jon Halapio
For depth purposes, bringing in another guard through this late in the draft makes sense. Chris DeGeare is the only listed backup for Bernadeau and Leary on ESPN's projected 2014 depth chart. Halapio is someone Dallas can develop and be a last resort kind of option at guard next year.
Round 7, Pick No. 251: Matt Patchan
The offensive tackle position is a bit more stable, but Patchan would be a great depth guy. He stands 6'6" and weighs in at 302 pounds. The Boston College product has ideal size and moves pretty quickly for a guy that big. Patchan would be a nice backup to have on the roster.
Round 7, Pick No. 254: Chris Whaley
Going back to Texas, Dallas will probably look back to defensive tackle with its last pick, specifically Chris Whaley. He's an athletic lineman that knows how to stay on his feet. There's some real raw talent here that Marinelli might be able to mold.
