2015 NFL Mock Draft: Stock Watch and Predictions for Combine's Top Prospects

The real stock market has nothing on the NFL's version this time of year. 

Influenced by a whirlwind of stopwatches, drills, interviews, public perception and more, the stock of the top prospects in the 2015 NFL draft forever changes due to the events in Indianapolis at the NFL Scouting Combine.

Before the event that spans multiple days started, the mock-draft realm was relatively quiet.

Now, not so much. Surprising performances, disappointments and more change the complexion of the stock market by the second, and with it the ripple effect on the entire draft as a whole.

As things wind down in Indianapolis, be sure to review an updated look at how the first round figures to shake out.

Stock Watch and Predictions for Notable Names on the Move

DeVante Parker, WR, Louisville

Jot it down in permanent marker—Louisville's DeVante Parker is a top-15 pick.

Parker, who caught 43 passes for 855 yards and five scores in limited action last year, weighed in at 6'3" and 209 pounds before taking off for a 4.45 40-yard dash.

Bleacher Report's Matt Miller is one of many to sing Parker's praises after such a size-speed display:

Yes, Parker has always been in the discussion for the first round, late at worst. But whispers of his contention with the draft's top names such as Heisman Trophy finalist Amari Cooper and Kevin White never came with much in the way of proof.

Now the whispers are screams with plenty of reinforcements.

There are now measurements next to Parker's impressive tape, which ensures he will be one of the first wideouts off the board in the first round. His physical set of skills are difficult to find, and his sure hands and proven ability to stretch defenses deep is a difference every offense needs.

With that in mind, look for the Cleveland Browns to nab Parker with the first of their two first-round picks. No matter who resides under center, the team needs a fresh start at the position.

Prediction: Cleveland selects Parker at No. 12 overall. 

Vic Beasley, DE/OLB, Clemson

So much for that talk about Clemson's Vic Beasley being too small.

Beasley weighed in at 6'3" and 246 pounds, a staggering size for a player who most considered a major risk despite his elite explosiveness off the line.

Once the weight concerns evaporated, the cloud then moved to Beasley's ability to retain said explosiveness off the snap now that he carries a bigger frame. 

Beasley put it all to bed, as Miller notes:

An exercise by the NFL's Twitter account puts things into a fun perspective:

There is no stopping Beasley's immense climb up draft boards at this point. His elite ability off the edge on film against collegiate competition is one thing. His ability to add sheer muscle to his frame without suffering a hit in the speed department is something that sets him apart at the next level.

Look for Beasley to land somewhere such as New Orleans, where defensive coordinator Rob Ryan will use his elite athleticism at multiple positions to keep offenses guessing.

Prediction: New Orleans selects Beasley at No. 13 overall. 

Dorial Green-Beckham, WR, Oklahoma

The most controversial prospect in this year's class is not really Jameis Winston, but Dorial Green-Beckham.

As is the case with Winston, it does not seem worth the time to get into a long spiel concerning DGB's off-field concerns at this point. As the video above shows, too, it seems the star wideout's redemption tour is beginning without a hitch.

The on-field package is what has always made DGB a first-round lock. He comes in at 6'5" and 237 pounds, otherwise known as in the same mold as Calvin Johnson. Not only that, he ran a 4.49 40-yard dash.

NFL.com's Chris Trapasso puts it best:

DGB can clearly run with the biggest defenders in the league. He can outbox them at the first-down marker, in the red zone and really anywhere on the field. His routes are clean, hands consistent. His catch radius is unmatched in the class.

In reality, DGB figures to be one of the biggest shocks of the 2015 draft. When a team has a shot at a Dez Bryant-esque talent in the potential department, it will take it—especially if said team is attempting to bring along a promising youngster such as Teddy Bridgewater.

Prediction: Minnesota selects DGB at No. 11 overall.
