NFL Mock Draft 2019: 1st-Round Projections for Top Prospects Before Combine

The NFL Scouting Combine is one of the most anticipated events on the offseason calendar, and the testing event will affect the perception of several top prospects.

Perform well, and a draft stock can surge. Compare unfavorably to others at the position, and a drop could be coming.

Either way, the result is similar: changes on the mock draft.

While this is a fluid process anyway, what appears on this first-round preview―which is based on best player available, roster fit and no trades―could have a fresh look after the combine.

D.K. Metcalf, WR, Ole Miss

Ah, yes. Beautiful February day outside. Hey, has anyone seen how D.K. Metcalf's recovery and preparation are going?

Oh. Well then.

Metcalf missed the last five games of 2018 due to a neck problem, but he was plenty productive before the injury. The wideout eclipsed the 80-yard mark in five of his six healthy appearances, including a pair of 100-yard showings.

Without question, NFL teams will be carefully assessing his medical readiness. However, the 21-year-old has been cleared for all activity and will participate in Indianapolis.

And if he tests out athletically as well as anticipated, a receiver-needy Washington team should come away impressed.

Rashan Gary can benefit immensely from the NFL Scouting Combine.

Coming out of high school, he was a 5-star prospect considered an athletic rarity for his position, but he seemed to leave some production on the field. During the last two seasons, the 21-year-old piled up 110 tackles with 19.5 tackles for loss and 9.5 sacks.

While the numbers are solid, he wasn't consistently a force against top competition. Because of that, some NFL teams may have a slightly less favorable view of Gary. Yet an impressive showing at the combine will remind them why he's a high-ceiling prospect.

He should appeal to the Tennessee Titans, who need to improve depth at both defensive end and tackle. He's most effective inside but could produce at either spot.

Tennessee, though, would be fortunate if Gary slid this far. He may emerge as a "winner" in Indianapolis.

The Colts could use an upgrade at receiver.

Andrew Luck has an obvious go-to target in T.Y. Hilton, but the No. 2 and No. 3 pass-catchers in 2018 were tight end Eric Ebron and Nyheim Hines. Although both Chester Rogers and Ryan Grant nabbed 30-plus passes, neither averaged more than 10 yards.

Kelvin Harmon, however, offers an important mix of reliability and big-play potential. According to Pro Football Focus, his 17 contested catches tied for eighth-most nationally and 27 plays of 20-plus yards tied for 19th last season.

On skills and potential, he's worth a first-round selection. Still, the draft is largely based on value. If there isn't a run on receivers early, the 21-year-old could slide into Day 2 territory.

But if he thrives at the combine, Harmon will demand the Colts' attention when they're on the clock.
