NFL Draft 2015: Prospects Primed to Surge Up Rankings in Coming Months

The second the NFL season officially ends, draft season begins.

Each and every year, the machine kicks into high gear. Some prospects are trashed anonymously to the media, while others blow everybody away during workouts, thus moving up many teams' draft boards.

The three players below should all see their respective stocks rise in the coming months. They've got the combination of athleticism and talent that will be impossible to ignore.

Cedric Ogbuehi, OT, Texas A&M

Remember how Greg Robinson seemed to come from out of nowhere and be the second overall pick in the 2014 draft? To a certain extent, that could be Cedric Ogbuehi.

Ogbuehi doesn't have nearly as far to climb as Robinson did, but, like Robinson, you could easily see the Texas A&M offensive tackle shine at the scouting combine and the Aggies' pro day. Those performances could move Ogbuehi into the top 10 and potentially top five.

Ogbuehi's stock dropped a bit during the 2014 season due to underwhelming performance. Technically, he leaves a little bit to be desired and still needs some work. Athletically, he's exactly the player teams look for in a left tackle—light on his feet but possessing enough strength to overpower defenders at the point of attack.

Back on Dec. 19, Bleacher Report's NFL draft expert Matt Miller wrote that a strong game against LSU helped Ogbuehi bolster his standing among this year's crop of tackles:

"

Texas A&M tackle Cedric Ogbuehi started the year as a potential top-10 pick but struggled at left tackle and saw his stock drop some. But against LSU, and against future NFL defensive end Danielle Hunter, Ogbuehi was dominant. This is a game two NFL scouts pointed out to me this week as proof that Ogbuehi is still a top-15 player.

"

Teams will fall in love with Ogbuehi all over again when they watch him at the combine.

Lynden Trail, OLB, Norfolk State

Lynden Trail isn't a complete unknown for diehard SEC fans. He was originally a member of the Florida Gators before transferring to Norfolk State in 2011.

According to 247Sports' Trail was the eighth-best weak-side defensive end in the 2010 recruiting class, illustrating how much potential he showed coming out of high school.

Playing for the Spartans always meant that Trail would get overshadowed a bit by stars from bigger schools, but it hasn't prevented him from getting noticed by NFL teams. Norfolk State head coach Pete Adrian explained how much attention Trail's drawn this year, per ESPN.com's Donald Hunt:

"

This is the second or third time, probably the fourth time, in my years as a coach here we've had a player who will probably be selected in the top three rounds. That's what happens at this level. We've had over 100 scouts here at the start of the season.

We get three, four, five a day. Now, we're getting people back for the third and fourth time. We've had heads of scouting, assistant GMs and all that stuff. They want make sure a player who plays at this level of competition can go on and play at the next level. I give Lynden a lot of credit. He's staying focused and thinking about the football season and letting cards fall where they may.

"

It's always difficult grading a player from the FCS level because the competition is a small step down from FBS.

With the combine, Trail has a chance to measure up with the best in the country. He's not an otherworldly athlete, but he should silence some doubters who question if he has the tools to succeed in the NFL.

NFLDraftScout.com's Dane Brugler praised Trail in a scouting report he wrote about the linebacker back in November:

"

Trail certainly passes the eye test with his tall, lengthy frame, but he also looks the part in motion, showing impressive movement skills for his body type. He is a flexible athlete with smooth change of direction skills and long strides to accelerate quickly in pursuit. Trail has the body bend to dip and run the arc at 45-degree angle without losing speed, displaying good get-off quickness and a consistent motor. He uses his length well to corral ballcarriers and is at his best when he extends at the point of attack to properly work off blocks.

"

CBSSports.com projects Trail as a fourth-rounder and 129th-best player overall. It would be quite a leap for him to get into the first round. As the draft approaches, you'll hear his name more and more, and a late second-round pick doesn't seem out of the question.

Stefon Diggs, WR, Maryland

USA TODAY Sports

You can't help but look back on Stefon Diggs' college career and wonder what could've been after the Maryland wide receiver missed nine games over the past two seasons.

Despite his injury problems and the Terrapins' rather pedestrian offense, Diggs still finished with 150 receptions, 2,227 yards and 14 touchdowns in his three years with the school.

He announced on Saturday that he'd skip his senior season and head to the NFL.

"After talking with my family during the past few days, I have decided to enter the NFL draft," he said, per The Baltimore Sun's Matt Zenitz. "We really thought about everything and weighed the pros and cons of staying at Maryland versus entering the draft, and we decided that this is the best decision for me."

Miller said on Twitter that Diggs could've used another season in college:

CBSSports.com is similarly low on the Terps star, listing him as the 20th-best WR and a fourth-round pick.

Diggs is one of the most explosive wide receivers in the draft. He's kind of player who turns a 10-yard slant into an 80-yard touchdown.

The injuries are a bit of a concern, but his somewhat sloppy route running can be cured. Just look at how Demaryius Thomas grew after getting pushed by Peyton Manning. Diggs isn't the same caliber of player Thomas was in college, but the general rule applies.

Every year, you see teams reach for a receiver who possesses ungodly speed but isn't anywhere near the finished product. It's a stretch to say that Diggs will be considered a first-rounder by the time the draft rolls around, but it wouldn't be a surprise to see him off the board early on Day 2.
