The Dallas Cowboys are no strangers to draft-day trades, as owner Jerry Jones loves to maneuver and manipulate the draft to find the best talents possible. Since Jimmy Johnson's departure in 1994, Jones has manufactured 27 trades involving top-100 picks.

Unlike a lot of teams, the Cowboys aren't afraid to trade up to grab talent early (Morris Claiborne and DeMarcus Lawrence) or late (Xavier Woods) in the draft. If they don't like the value available when they go on the clock, they are comfortable trading back to accumulate more picks, which is how they landed Travis Frederick in the 2013. The Cowboys aren't afraid to include players in draft trades, either, as evidenced by their moves involving Jamize Olawale, Tavon Austin and Ryan Switzer last year.

The Cowboys are devoid of a first-round pick this year because of the Amari Cooper trade, and they aren't likely to give up the assets necessary to trade back into Round 1. Nevertheless, you can be assured that Jerry Jones and the rest of the Cowboys' draft room will be working the phones heavily throughout the remainder of the draft.

With that in mind, let's take a look at three potential trades that would make sense for the Cowboys in this week's draft.

Trade up in Round 2 for a safety

It's no secret the Cowboys are looking to upgrade the safety position. They brought six safeties -- Florida's Chauncey Gardner-Johnson, Mississippi State's Johnathan Abram, Washington's Taylor Rapp, Virginia's Juan Thornhill, Boston College's Will Harris and Michigan State's Khari Willis -- to The Star in Frisco among their 30 allotted pre-draft visits.

While Willis and Harris are more mid-to-late round options, Gardner-Johnson, Abram, Rapp and Thornhill are likely targets at pick No. 58. Unfortunately for the Cowboys, there a lot of teams in front of them that could use an upgrade at safety as well.

According to The Draft Network, there are nine teams that have safety as a primary need entering the draft and five others have safety as a secondary need, which means there's a decent chance the Cowboys' preferred safety options are gone by the time they go on the clock toward the end of Round 2.

According to Drafttek's trade value chart, the Cowboys have enough ammunition with their second- and third-round picks to move all the way up to the 44th overall pick. This means they could consider trading up to grab one of their preferred safety targets.

Giving up a second- and third-round pick for a rookie safety is a tough pill to swallow, but it would allow the Cowboys to upgrade and improve the depth of one of their least-talented position groups.

If they decide that adding a third-round pick is too steep, they could also trade up into the early 50s using the first of their two fourth-round picks (No. 128), which should be a much easier pill to swallow.

In a perfect world, the Cowboys would be able to stay put at 58 and upgrade the safety position with Gardner-Johnson, Rapp or Thornhill (sorry, Abram), but if the board starts to break unfavorably, they have to consider making a small jump up to secure a safety.

Trade Jourdan Lewis for a Day 3 pick

If there is a player on the Cowboys' roster who could use a change of scenery, it's Jourdan Lewis.

After being selected in the third round of the 2017 draft, Lewis had an impressive rookie year in which he started seven games, accumulating 10 pass deflections and an interception. Unfortunately for him, that super debut wasn't rewarded when the team hired former Seattle defensive coordinator Kris Richard, who values size and length in his cornerbacks.

Ideally, Richard wants his cornerbacks to be above 6 feet, over 195 pounds with 32-plus-inch arms -- at 5-10, 195 pounds with 31 5/8-inch arms, Lewis comes up short in almost every respect. Because of this and Byron Jones' full-time switch to cornerback, Lewis' role was drastically decreased last season (he played 553 fewer snaps than in 2017, according to Pro Football Focus).

Though he's not a great fit in Richard's scheme, Lewis still provided value when he was out there, as evidenced by his performance against New Orleans, when he did an outstanding job covering Alvin Kamara out of the backfield.

Lewis is too talented of a player to rank No. 4 on the cornerback depth chart (behind Jones, Chidobe Awuzie and Anthony Brown), which is why it would make sense for Dallas to trade him. The Cowboys reportedly "lightly shopped" Lewis at the end of the 2018 preseason.

Where there is smoke, there usually is fire, and even though Dallas hasn't pulled the trigger on a Lewis trade, it's something the team has definitely considered and will likely continue to consider moving forward.

If the Cowboys draft a cornerback in the second or third round, which is a possibility given the interest they have shown in cornerbacks (Richard has traveled to Vanderbilt and Houston to meet with and work out Joejuan Williams and Isaiah Johnson), it makes the possibility of trading Lewis all the more likely.

Because Lewis is so low on the depth chart, it's unlikely Dallas would get anything more than a Day 3 pick for him, which is a tough pill to swallow since his talent is far superior than what a Day 3 pick usually brings back.

Still, given the depth at the cornerback position, it's a move the Cowboys can easily absorb without taking too much of a hit.

Trading Lewis could be a win-win for both parties. The Cowboys get more draft capital, giving them more flexibility to trade and maneuver throughout Day 3 of the draft, and Lewis, in theory, gets more playing time for a team that provides a better scheme fit.

Don't be surprised if rumors start to swirl that Dallas is once again shopping Lewis this weekend.

Trade down in Round 3 to regainlost sixth-round pick

The Cowboys don't have a sixth-round pick this year because of the Bene Benwikere trade in 2017, which netted them a cornerback who saw just 11 defensive snaps throughout his stay in Dallas.

The absence of a sixth-round pick is nothing to fret over, but the Cowboys could opt to make a small trade down in the third round and net a sixth-rounder if they don't like the value available when pick No. 90 is up.

According to Drafttek's trade value chart, the Cowboys would only need to drop five spots from their third-round slot (No. 90 overall) to get a high sixth-round pick in return, three spots to net a mid-sixth-rounder, or just two spots to gain a late sixth-rounder.

The Cowboys have been one of the more successful teams with their sixth-round picks as of late, selecting valuable contributors in Woods and Brown in recent drafts. In 2018, they selected wide receiver Cedrick Wilson and linebacker Chris Covington in the sixth round and both remain with the team a year later (though Wilson missed all of last season with an injury).

While it's not a sexy move that will grab headlines, these types of pick swaps are the lifeblood of the NFL draft on Days 2 and 3, and you can expect that Trader Jerry will want to make some noise.
