It's been a couple of weeks since my last mock for the Cowboys, but not much has changed in terms of the team's needs. The secondary is the primary concern, while the pass rush, o-line, and tight end spots could all use a boost. (My first mock of the year, done pre-Combine and mostly horribly out of date now, is here.)

I deliberately zagged when I'd previously zigged on a couple of the earlier picks here, just to see how the player pool shook out, but for the most part I think the talent haul ended up being similar to the prior mock. It might take a couple more weeks, and the completion of all the Pro Days, for there to be any significant changes in rankings that might radically alter how these mocks play out.

This one was done using Fanspeak's own Big Board, with the user-voted team needs.

Round 1 (pick 28): Marcus Williams, S, Utah. The top safety on the board by SPARQ score (get used to seeing that phrase), Williams won't be a replacement for Barry Church as a box safety and big hitter. Instead, he's a pure old-school free safety who can rack up picks with his closing speed, size and leaping ability. He's also not a terrible tackler when it comes to technique, although it could be a couple of years in an NFL weight room before he'll be able to do more than slow down some of the more physical receivers in the league in a one-on-one clash. Williams figures to combine with Byron Jones to give the Cowboys the back-end support the defense will need in an increasingly pass-happy NFC East, while Jeff Heath can still fill Church's old role on running downs.

Round 2 (pick 60): Ahkello Witherspoon, CB, Colorado. While there were some interesting edge rushers still on the board here, Jordan Willis (my previous 2nd round pick) was gone and I'm not a fan of Carl Lawson's injury history, so I went back to the secondary. One of the top corners on the board by SPARQ score, Witherspoon has great size and length, ran a 4.45 40-yard at the Combine, and showed rapidly improving instincts in college after a bit of a late start to his football career -- in high school he was a little 5-foot-8 shrimp before a growth spurt made football a viable career path for him. Oh, he's also got the brains to be a defensive captain down the road. Had it not been for that growth spurt, Witherspoon was on a pre-med track. Like Williams, he'll need to get stronger and work on his tackling, but one of the hallmarks of Rod Marinelli's defense is group effort and swarming the ball carrier. Just so long as the first guy on the scene can slow him down, the cavalry will bail him out. A DB's first job is to stop the completion before the receiver becomes a ball carrier, and that's where Witherspoon excels.

Round 3 (pick 92): Tyus Bowser, DE, Houston. The top edge rusher on the board by SPARQ score, Bowser is a former basketball player whose football skills are still raw, and he may not have the size to develop into an every-down DE in a 4-3 scheme. His tape and college production also don't match his athletic profile, making him a possible workout warrior bust. All that said, he showed tremendous improvement between 2015 and 2016 and could easily find a fit in Dallas as a sub package pass rusher, special teams player and occasional linebacker.

Round 4 (pick 133): George Kittle, TE, Iowa. Kittle doesn't have a complete SPARQ score yet, but a 4.52 40-yard dash, 35-inch vertical and 11-foot broad jump suggest he'll rank among the elite at his position once his Pro Day has filled in the gaps. He's a willing, even eager, blocker with good hands as a receiver, and while he's maybe a bit undersized to be a full-time in-line tight end, he's about the same size as current Cowboy Geoff Swaim was coming out of school, and Kittle has the frame to add some weight. He's the kind of hard-nosed player who could grow immeasurably by getting to learn at the feet of a Hall of Famer like Jason Witten for a season or two, and last summer Pro Football Focus had him rated as the top all-around tight end in college. Even in the fourth round, I consider him a steal -- much as Witten was a third-round steal back in his day.

Round 6 (pick 211): Levon Myers, OT, Northern Illinois. This isn't exactly a typical Cowboys pick, as he's not from a power conference school and doesn't have great athletic measurables, but as a developmental tackle he's got some things going for him. He reportedly posted a 7.52 in the 3-cone drill at his Pro Day, which is a crazy number for a 300-pound lineman (it would have been tied for second among all O-lineman at this year's Combine), and his tape backs up the idea that Myers has the mobility Dallas likes on their line. He also plays with an edge, which is nice to see and not isn't something you can teach. He's got some issues in technique which will need to be cleaned up and won't necessarily compete for snaps right away, but he could be the team's Week 1 starter at right tackle in 2018 if Chaz Green doesn't pan out.

Round 7 (pick 228): Shaquill Griffin, CB, Central Florida. No. 3 among corners by SPARQ score on this year's board (Witherspoon was No. 4), I can pretty much guarantee Griffin won't last until the seventh round in the actual draft after running a 4.38 40-yard at the Combine, but mocks gonna mock. He offers a physical element to his game that the previous two secondary picks lacked, and you have to like the 32.9 percent completion percentage he allowed in his final year. He's got some technique issues in coverage and his instincts look a bit shaky on tape, which didn't allow his speed to translate into coverage all the time, but the tools are there for him to be an NFL starter.

Round 7 (pick 246): Jehu Chesson, WR, Michigan. I'm just going to keep scooping him up in the late rounds of mock drafts until his stock starts to rise. One of the top wide receivers on the board by SPARQ score, Chesson looked pretty darn good in 2015 before injuring his knee in the Citrus Bowl but wasn't the same player at all in 2016, lacking any kind of explosiveness or ability to separate. However, he excelled at the Combine, running a 4.47 40-yard, and then backed up that performance at Michigan's Pro Day, so it's possible he just needed extra time to put the knee injury behind him. He's got the size and physicality the Cowboys like in their WRs, so taking a chance the 2015 version of Chesson has returned is well worth a seventh-round gamble.
