With the first wave of free agency over, the conservative Dallas Cowboys may now get a little more active with players still on the open market. What are the biggest remaining roster needs that they could address in free agency before turning to the 2021 NFL Draft?

Dallas has been scratching the bottom of the free agent barrel after signing Dak Prescott, despite his only counting $22.2 million against the cap for this season. They've gone with their ‘business as usual' approach to free agency, allowing the top talent to sign elsewhere and instead go for the next tier of free agents, sign them to low-cost, one-year deals.

Rinse and repeat.

Nevertheless, the Cowboys have managed to sign some worthwhile players who might be starters, or maybe just solid rotational players for the team in 2021.

Where the frustration comes from is the Cowboys having the money and cap flexibility to be able to pay players like Carl Lawson or Patrick Peterson. They've passed on guys who would immediately make the team better, opting instead for cheaper players as one-year rentals.

Thankfully, free agency isn't over.  There are still notable spots that need to be filled before the draft and viable options available.

Nose Tackle

Adding players like Carlos Watkins and Brent Urban to the defensive tackle rotation should offer more depth. But outside of Antwaun Woods the team lacks a second, true nose tackle.

Urban and Watkins should be able to flex between both tackle spots but both could also end up being camp bodies who ultimately don't even make the final roster. Free agency still has plenty of veteran options available that the Cowboys need to consider.

Players like DaQuan Jones and Danny Shelton are both still available and either one would upgrade the position going into the draft.

Cornerback

With the Anthony Brown still here and the re-signings of Jourdan Lewis and C.J. Goodwin, the Cowboys have depth at corner. The issue is who's going to start opposite Trevon Diggs at the outside corner position.

Chidobe Awuzie signed with Cincinnati in free agency and more starting corners are being swept up each day; Adoree' Jackson is off to New York, Malcolm Butler to Arizona and Patrick Peterson to Minnesota. Players like Casey Hayward, Darqueze Dennard and Richard Sherman are all still available and would easily become the in-place starter and veteran presence the team needs.

Cornerback is a need the team probably plans to address with either the 10th or 44th overall picks. Still, the Cowboys had one of the worst defenses in the league in 2020 and need to make sure they've got a reliable starter at corner if their draft pick isn't ready for whatever reason.

Edge Rusher

Signing Tarell Basham is good for depth for two key reasons: the Cowboys, reportedly won't re-sign Aldon Smith, and he's coming off his best season with 3.5 sacks and five tackles for loss. Outside of him, and starters DeMarcus Lawrence and Randy Gregory, the edge rushers on the team are raw.

Dorance Armstrong has flashed but hasn't shown much consistency in his three seasons with the team. Bradley Anae has some high upside but was seldom used in his rookie season. Ron'dell Carter was limited to three games as an undrafted free agent, but the team believed in him enough to extend the ERFA tender.

The Cowboys are likely to take an edge rusher in the draft, even though it's not one of their biggest pressing needs. With players like Carl Lawson and Trey Hendrickson being too rich for their taste, a lesser-known talent like Denver's DeMarcus Walker might come in at the right price.

Punt Returner

A need that keeps being experimented with is punt returner. The team hasn't had a consistent, reliable punt return option since Dwayne Harris. Last year's first round pick CeeDee Lamb was the team's primary option in the return game, but as his offensive importance increases then special teams usage should go down.

Special Teams coordinator John Fassel seems to be recreating the same elite special teams he had in L.A. with kicker Greg Zuerlein and the addition of Jake McQuaid as long-snapper. It's possible he could also want to reunite with his former All-Pro returner Pharoh Cooper.

Aside from him, the best return-man of the last decade, Cordarrelle Patterson, is looking for a new home and would be a welcomed addition to both the punt and kick return teams.

It's not a need that gets looked at much, but like free safety, is a need that is continuously overlooked and has underwhelmed.
