NFL Draft 2015: Latest Mock Draft and Prospects on the Rise as Pro Days Conclude

The end of the lengthy pro-day process signals one thing—the 2015 NFL draft is right around the corner. 

This year's set of pro days proved as entertaining as ever. Media circuses around Marcus Mariota and Jameis Winston created wild environments, while lesser-known players such as Auburn's Corey Grant used hand times instead of electronic ones to post blazing 40-yard dashes and make a name for themselves.

The tail end of the schedule saw some major programs step forward with their prospects on a big stage, and the result is more stock movement and a shuffling of the first-round projections.

Below, let's take a look at three of the most recent winners after an updated mock draft.

Latest Pro Day and Stock Winners 

La'el Collins, OT, LSU

In a bit of an odd class for offensive tackles, La'el Collins' stock has been one of the most erratic.

He was first considered a candidate for the right side or interior but not on the left. He seemed to put some of those assumptions to bed by showing up at the NFL Scouting Combine at 6'4" and 305 pounds with strong marks in most athleticism drills.

Still, the performance wasn't enough to convince the globe he should be above Brandon Scherff or Andrus Peat.

The tune seems to be changing, though, thanks to LSU's pro day, where NFL.com's Bryan Fischer notes Collins "looked plenty athletic during offensive line drills."

To top it all off, Bleacher Report's Brent Sobleski notes Collins showed up even heavier:

Favorable measurements in a familiar environment or not, Collins' stock seems cemented at this point.

No matter what else happens on the path to the draft, he is a first-round pick based on his ability to bulldoze defenders from the right side of the line. If coaching staffs feel they can unlock the physical potential he flashes, he'll go off the board higher than expected and get a shot on the left side of a line.

A.J. Cann, OG, South Carolina

Long considered the top interior offensive lineman in a weak class, South Carolina's A.J. Cann did nothing short of help himself at his pro day.

NFL teams in need might now have an excuse to draft him in the first round.

The biggest knock on Cann is size, considering he showed up at the combine at just 6'3" and 313 pounds. Elite athleticism can make lack of size a moot point, though, which is what Cann shows on film.

As Fischer records, Cann showed NFL teams at his pro day he can man center: "Still, there were a handful of draft picks in action, and Cann really stood out with his workout. In addition to moving well, he showed teams his versatility by playing center as well as guard."

It's an added wrinkle of versatility that teams love to see. Offensive guards don't go in the first round often due to value, but Cann seems to have the total package. A scarcity at the position may scare a team into calling his name in the opening round.

Regardless, Cann's pro day cemented the notion he's an instant NFL starter.

Mario Edwards Jr., DE, Florida State

Consider Mario Edwards Jr. a new arrival to first-round chatter. 

He has been on the cusp for a while now, as the scheme-versatile presence measured in at 6'3" and 279 pounds at the combine before performing well in all athleticism drills.

It says quite a lot about Edwards as a prospect when he manages to capture the attention of the NFL and media at the same pro day as Winston. Yahoo Sports' Charles Robinson is one of many to label Edwards a big winner of the showcase:

Edwards didn't put on impressive tape at the collegiate level in most games. As an AFC West scout told NFL.com's Lance Zierlein at the combine, "I think conditioning and desire are a big problem for him, and they go hand-in-hand. He just looks content to stay blocked by lesser players, and it is so frustrating to watch because you know he has the talent to be so much better."

The tide seems to be turning in Edwards' favor. He's one of the better players in the class, and a coaching staff that believes it can unlock his potential might pull the trigger on him in the first round.
