The Cowboys' coaches and scouts enter this year's NFL scouting combine with an advantage over almost every other team. Last month they spent a week with several of this year's top draft prospects at the Senior Bowl.

But of those players, North Dakota State quarterback Carson Wentz and Eastern Kentucky defensive end Noah Spence are probably the only ones the Cowboys would realistically consider with their fourth overall pick in April.

It's likely that the player the Cowboys select in the first round will be someone they meet for the first time this week in Indianapolis.

Here are six prospects to keep an eye on and the positives and negatives to consider about each:

Joey Bosa

DE, Ohio State

Pros: Getting to the quarterback has been one of the Cowboys' biggest problems for two seasons. Bosa has been one of college football's most productive pass rushers, totaling 26 sacks over the last three years. In the Cowboys' 4-3 scheme, Bosa is versatile enough to play left defensive end on first and second downs, then move to defensive tackle on third downs.

Cons: For a defensive end to be a top-five pick, he usually needs to be an elite pass-rushing right end. Bosa is not that. He's a high-motor player who will be very good against the run and a solid pass rusher. If the Cowboys pick him at No. 4, will they be fine with a player who might be good for a long time but never become a star?

Ezekiel Elliott

Pros: He's the consensus top running back in this class and the only one projected to go in the first round. Todd Gurley was in a similar situation last year. The Georgia standout ended up going 10th overall to St. Louis. He finished third in rushing with 1,106 yards. Running behind the Cowboys' offensive line, a complete back like Elliott could become a perennial Pro Bowler.

Cons: No. 4 might be a little too expensive for a running back. Since 2007, Darren McFadden and Trent Richardson are the only running backs to be drafted in the top five. Some think many backs would have success running behind the Cowboys' line, so why not aim for quality production out of a player selected in the second or third round?

Jared Goff

QB, California

Pros: He's regarded by many as the top quarterback in this class. Goff has the ideal size, arm talent and mobility to be a starting NFL quarterback. As a junior last season, the 6-4, 215-pound Goff put up huge numbers in the Pac-12, throwing for 4,719 yards, 43 touchdowns and 13 interceptions. If he doesn't go to Cleveland, at No. 2 he's likely to be available at No. 4.

Cons: Goff played in an up-tempo spread offense at Cal that had him in the shotgun most of the time. He'll have to adapt to playing under center much more at the NFL level. Drafting a quarterback is unlikely to help the Cowboys immediately, so picking Goff at No. 4 means passing on a player who could help maximize Tony Romo's remaining time as Dallas' franchise quarterback.

Myles Jack

LB, UCLA

Pros: In a league where linebackers are routinely required to defend tight ends and running backs in the passing game, Jack is the ideal fit. He's such an exceptional athlete that he was able to play running back and linebacker at UCLA. With the Cowboys, Jack would be a three-down middle linebacker, teaming with Sean Lee to potentially form one of the best playmaking duos in the league.

Cons: Jack has played only 28 college games. He appeared in only three last season because of a torn meniscus. Since Jack is still rehabbing from the injury, it was recently reported that he won't be able to fully participate in the combine. At 6-1, 245 pounds, Jack doesn't have the prototypical size that teams look for in linebackers.

Paxton Lynch

QB, Memphis

Pros: The 6-7 Lynch won't have any trouble seeing over an NFL offensive line. His athleticism and mobility should allow him to be able to escape pressure at the pro level. Although he didn't play in a "power five" conference, Lynch was very good the last two years in games against UCLA, Kansas and Mississippi. Lynch helped upset Ole Miss last year, throwing for 384 yards and three touchdowns.

Cons: Like Goff, Lynch comes from playing in a spread system. Unlike Goff, Lynch is considered a project who will need time to transition to an NFL offense. His mechanics aren't nearly as polished as Goff's, either. Lynch wasn't very good in his final college game, completing only 16 of 37 passes for 106 yards and one interception in a 31-10 loss to Auburn.

Jalen Ramsey

Pros: He's such an outstanding athlete that many experts consider him to be this draft's top corner and best safety prospect. Cowboys defensive back Byron Jones' stock skyrocketed after putting up huge numbers at last year's scouting combine. Ramsey, who is already projected to be a top-five pick, could increase his stock even more if he performs the way experts are predicting.

Cons: His best position in the NFL could be as a safety, but the Cowboys would likely draft him at No. 4 to be a cornerback. Ramsey played both during his three seasons at Florida State. While Ramsey has the ideal size (6-1, 200 pounds) and athletic ability to become a shutdown corner, he failed to record an interception at the position last season.
