With the majority of pre-draft visits out of the way, we've hit the lull before the NFL draft. Once the Dallas Cowboys locked up DeMarcus Lawrence to a big-money extension, they put themselves in position to focus entirely on improving their team in the draft.

Without further ado, let's grade our next crop of Cowboys pre-draft visitors, including a few potential Day 3 targets.

Note: These grades are the individual evaluations of the author and not meant to predict the Cowboys' grade, or where the player may be drafted. Here's the link to the grading scale being used. Additionally, here's the source of the pre-draft visits.

Khari Willis, S, Michigan State

Khari Willis is another versatile safety who shows the ability to be effective in a variety of alignments.

Measuring in at 5-foot-10, 213 pounds, Willis played all over the Michigan State defense, taking significant snaps at slot cornerback, free safety and strong safety.

He displays impressive man-coverage ability from the slot, showing good physicality to disrupt the timing of routes and stay in-phase with receivers through the break point. Despite his lack of height, Willis' physicality in the contact window leads to a lot of success against tight ends in coverage. He does an excellent job of using light contact to "feel" the routes of receivers, which aids him in anticipating breaks and limiting separation.

Willis gets too handsy at the break point at times, which will lead to a lot of flags in the NFL if he doesn't get that cleaned up.

He demonstrates plus instincts from shallow zone coverage. He understands how to read the quarterback's eyes, enabling him to anticipate route combinations and make plus-breaks on the ball.

But despite showing great anticipation in shallow zones, Willis showcases average range when aligned deep, as he possesses average athleticism and is a tick slow to process from the deep middle. He's much more comfortable from split-safety alignments, where he has to cover less ground quickly.

Against the run, Willis is a fundamentally sound defender who displays impressive closing burst and open-field tackling ability. He's not afraid to throw his body around, filling aggressively from space and attacking alleys in the box. Willis excels at attacking the alley to make plays on perimeter runs, as he leverages his 4.52 speed to chase ball carriers toward the boundary.

But because he is aggressive when filling from space, it causes him to be susceptible to play-action passes on occasion.

Willis tends to struggle most when he's forced to play through blocks, as he is severely underdeveloped at getting off blocks at the point of attack.

Khari Willis is another likable safety who DAL brought in as a 30 visit.

Willis displays advanced tackling technique, doing a good job of countering stiff arms at the tackle point. Even though he is aggressive in his pursuit of ball carriers against the run, he lacks the strike power to strike fear into opposing teams. At times, he will get too high at the tackle point, which allows ball carriers to churn an extra yard or two before being dragged down.

When he comes to balance at the tackle point, Willis is an impressive open-field tackler. Unfortunately, he has a tendency to arrive at the tackle point with too much momentum, causing him to slide off tackles on occasion.

All in all, Willis provides Dallas with a nice safety blanket (pun intended) if they strike out on the position on Day 2. He would be an immediate upgrade over Kavon Frazier as a reserve safety, possessing similarly strong special-teams ability to go along with vastly superior coverage skills, and could vie for the starting strong safety job in Year 2 or 3.

Willis isn't the flashiest safety or biggest playmaker, but he is a solid and versatile defensive back who can improve depth.

GRADE : 7.07 (Round 4)

Chris Westry, CB, Kentucky

Cornerback Chris Westry is one of the biggest sleepers in the draft because he wasn't even a starter during his senior season at Kentucky. Despite his lack of playing time, he was effective when on the field, yielding nine catches on 15 targets for 127 yards and two passes defensed, according to Pro Football Focus. Quarterbacks had a 77.3 passer rating when targeting Westry in 2018.

Measuring in at 6-4, 199 pounds, Westry possesses the frame and length that Cowboys defensive backs coach Kris Richard values in cornerbacks, though he could stand add a few pounds of bulk. On top of his impressive size, Westry is a freakishly explosive athlete, as he reportedly ran a 4.31 40-yard dash, jumped 10-foot-1 in the broad and 38 inches in the vertical.

With this type of frame, length, speed and explosiveness, he possesses prototypical size and athleticism for the Cowboys' scheme, having the speed to match vertical concepts along with the explosiveness and leaping ability to contest at the catch point.

Westry's agility times have yet to be released, but judging off his tape, they would have been much less impressive than his speed and explosion numbers. Like most tall cornerbacks, he struggles to change direction and transition fluidly to mirror receivers on breaking routes. Westry compounds these issues with his high pad level and clunky footwork.

Despite his length and speed, he tends to struggle in press coverage, lacking patience when jamming receivers at the line of scrimmage. Westry is easily manipulated by quick receivers, causing him to cede separation early in routes.

He is incredibly raw from a technical standpoint, but he displays the most comfort when playing press-bail in Cover 3 -- one of Dallas' favorite coverages -- as Westry can leverage his speed and length the match vertical concepts and condense throwing windows. Furthermore, his 4.31 speed shows up in his ability to recover when initially allowing separation. He is quick to rally and get in-phase with receivers.

Westry provides little value against the run, lacking physicality, and is content to let his teammates do all of the work. He is passive when taking on blocks and lacks adequate tackling technique. Westry's physicality needs significant improvement.

His enticing frame and athleticism make him an intriguing upside play for the Cowboys on Day 3. Westry isn't ready to contribute to an NFL defense, but Richard has proven to be one of the best coaches in the league at developing tall and lengthy cornerbacks who possesses salivating athletic traits.

If Westry can clean up his footwork and improve his physicality, he projects as a cornerback whose length can disrupt receivers at the line of scrimmage and whose speed can eliminate vertical concepts to the deep third of the field.

He is a lottery ticket who the Cowboys are uniquely positioned to take advantage of.

GRADE : 6.7 (Round 6)

Dre Greenlaw, LB, Arkansas

The Cowboys love to grab linebackers late in the draft, and Arkansas' Dre Greenlaw fits that bill.

Measuring in at 5-11, 237 pounds, Greenlaw is a fluid athlete who will be most valuable on special teams.

Because of his diminutive size, Greenlaw can get overwhelmed at the point of attack defending the run, lacking the bulk, length and play strength to effectively take on and shed blocks inside the box.

He compounds his issues taking on blocks with poor anticipation against the run, as he is slow to key, diagnose and flow play-side, enabling blockers to get inside his frame before he can generate momentum.

On top of his anticipation issues, Greenlaw displays poor vision when filling against the run, as he tends to run into blocks because he takes overaggressive angles toward ball carriers without being conscious of blockers.

To Greenlaw's credit, he is a reliable tackler -- finished his senior campaign with just four missed tackles -- who displays enough lateral quickness to be an effective open-field tackler.

Moreover, when he is able to free-flow to the ball carrier, he displays impressive pursuit speed, displaying the quickness to chase down runs to the perimeter.

Greenlaw also has notable upside in coverage because he has above-average range, showing impressive hip fluidity to turn and run with targets. He also showcases impressive lateral mobility to mirror crossing routes in shallow zones.

His lack of size and above-average athleticism limit his upside, as the bulk of his value comes as a special teams contributor. Greenlaw would be best suited as a target late on Day 3 or as a priority free agent if undrafted.

GRADE : 6.72 (Round 6)
