2015 NFL Combine Winners and Losers- Offense

Every year. The best and brightest college stars look to prove themselves worthy of an NFL contract. Today I rank the top winners and losers from the 2015 NFL Scouting Combine.

1. Jeremy Langford, RB, Michigan State- Even after posting back to back 1,000 rushing seasons, Langford's name wasn't mentioned as one of the top running back prospects. That should all change after the former Spartan posted a 4.42, 40 time which was the best among running backs. He showed great acceleration and burst in the on field drills. The effort will force NFL scouts to rewatch Langford's film and see how they missed his second gear speed. If it shows up on tape, he could see himself as a late second/early third round pick.

2. Kevin White, WR, West Virginia- The big knock on White was his in-game speed. The former Mountaineer put those thoughts to rest after he clocked in a 4.35 in the 40 and shined during the drills displaying great hands and ball skills. He looks the part as a premier number one receiver in every aspect. If he continues to work on his footwork and route running before his pro day, he may be the first wide out taken in the draft.

3. Dorial Green-Beckham, WR, Missouri/Oklahoma- After missing all of the 2014 due to transfer rules, everyone was awaiting Green-Beckham's workout. The standout wide receiver didn't disappoint running a 4.49, 40 time an showed great movement in drills. With Calvin Johnson like athleticism, DGB showed outstanding hands and ball skills. He showed the ability to track and adjust to balls in the air. With many teams needing a big number one option, scouts will have to look deep into his character issues to see if he is worth the risk.

4. Tyler Lockett, WR, Kansas State- The undersized playmaker continued to show he is worthy of being a day two pick. After a great senior bowl week, Lockett had an incredible Combine. He ran the 40 in 4.4 seconds and showed impressive explosiveness in receiver drills. Even more impressive was the former Wildcat's route running which was the best o any receiver at the combine as well as showing good balance, body control, and hands. He also is a versatile threat having return experience and is capable of running end arounds.

5. Maxx Williams, THE, Minnesota- His numbers won't blow scouts away, but his skill set still makes him the ideal starting tight end in the NFL. Williams showed he had the best pass catching ability of any tight end at the combine possessing strong hands and ball skills. He showed improved route running from his tape and is drawing comparisons to pro bowlers like Jason Whitten and Kyle Rudolph. Even though his athleticism is questionable, the Minnesota product showed he can be a consistent winner with his burst and quickness.

6. Jesse James, THE, Penn State- James has all the physical tools to be a lethal red zone weapon. He put on an impressive showing during drills and put up solid numbers in the vertical jump, broad jump, and bench press. The Penn State product displayed strong hands, natural ball skills, and can be a tough matchup anywhere he line up. Although he posted a less than ideal 40 time, he does have better athleticism than scouts expected and could make him one of the top five tight ends in the draft.

7. Andrus Peat, OT, Stanford- Peat quickly established himself as one of the top tackle prospects after the combine. He displayed a rare combination of athleticism and technical skill that could allow him to be a future left tackle at the pro level. The former Cardinal shined in athletic and positional drills displaying great balance, body control, and agility. Given his bulky lower body, Peat showed impressive lateral movement and quickness. With the lack of established edge blockers, Peat may be the first tackle off the board.

8. La' el Collins, OL, LSU- Collins has all the size, athleticism as a blocker, polished game, and temperament to be an ideal offensive lineman. He showed great agility and explosiveness during drills. He clocked in a 5.12 in the 40 which is certainly impressive for a 305 pound guy. He also displayed great balance, body control, and footwork. While the drills didn't display in game action, the fact that the former Tiger showed the strength, power, and agility of a blue collar prospect could make him an early first round pick.

1. David Cobb, RB, Minnesota- Cobb was in a talented class of Big Ten running backs. His performance at the combine was his chance to cement himself as a day two pick. Unfortunately for him, he drastically underperformed. The former Gopher, ran a pedestrian 4.81, 40 and didn't show anything else that would warrant praise. He appeared to lack speed, agility, and explosiveness during drills. Cobb will have to show more improvement at his pro day of he of going to be seen as more than a complementary back in an offense.

2. Ty Montgomery, WR, Stanford- He was expected to launch up draft board after the combine and instead he might have plummeted. Although he posted nice vertical and broad jumps, the former Cardinal failed to post an impressive 40 time and didn't look like an explosive athlete during drills. Montgomery also struggled catching passes without bobbling and didn't look like the play make he was on film. Depending on his pro day performance, the jury is still out if he can truly be an effective receiver in the pros.

3. Devin Funchess, WR/THE, Michigan- Funchess was seen as one of the most athletic hybrid prospects in the draft. After posting a 4.7, 40 time, scouts will question his ability to be a threat on the perimeter. The former Wolverine's lack of explosiveness may hinder him from separating from defensive backs and his lack of strength makes it tough to see him as a tight end. Therefore, unless he gets faster or stronger, he may not make it in the NFL.

4. Brandon Scherff, OL, Iowa- He might be the best offensive lineman in this years draft. Even though he posted an impressive 40 time at 5.05 seconds, Scherff couldn't capitalize on the buzz surrounding him. He suffered a hamstring injury early in drills and scouts never really got a good look at him. Although the strain is just a minor setback, he failed to answer questions concerning his athleticism, balance, and body control while also failing to show he can be an interior lineman. With the former Hawkeye's injury history, that will also be a concern for many scouts.

5. Clive Walford, THE, Miami- Walford was seen as one of the best receiving tight ends in the draft class. The former Hurricane failed to impress scouts with his pedestrian 4.79, 40 time and didn't show anything dynamic or athletic in drills. Although he posted good vertical and broad jump numbers to be a capable athlete he didn't show the skills to be a matchup nightmare on the perimeter or the strength to play on the inside.
