Offensive tackles

THE BEST

Name: Greg Robinson

School: Auburn

Height, weight: 6-5, 332

40 time: 4.92

225 bench: 32 reps

Arms: 35 inches

Round projection: 1

Mayock: "All three of the top tackles in this draft [Robinson, Jake Matthews and Taylor Lewan] are more highly rated than any of the tackles in last year's draft and Robinson is the best of the bunch. He has an awesome physical skill-set. He's young, but has the highest upside of any of the offensive linemen in this draft. When he grows into his body and figures it all out, he could be the best tackle in football with his physical skill set. He's just a little bit raw right now, but he's going to step in Day 1 and be somebody's starting left tackle for the next 10-12 years."

THE RISER

Name: Morgan Moses

School: Virginia

Height, weight: 6-6, 314

40 time: 5.35

225 bench: NA

Arms: 35 3/8 inches

Round projection: 2

Mayock: "Moses is a right tackle only. His length and ability to run-block has him rising up [draft] boards. He tested very poorly at the combine. But he's got some good tape and he's so darn long. And as teams decide which tackles to move to guard or center, this guy is slowly moving up boards to the point where he's going to be an early second-round pick."

THE SLEEPER

Name: Laurent Duvernay-Tardif

School: McGill (Canada)

Height, weight: 6-5, 310

40 time: 4.98

225 bench: NA

Arms: NA

Round projection: 5

Mayock: "This guy is intriguing. When he first got to college, he was a 250-pound three-technique [defensive tackle]. He's naturally grown into a longer, bigger body. He has athletic ability. He's intelligent. He went to the East-West game. Once he got himself acclimated there, his last couple of days of practice were pretty good. I think he's a right tackle, or somebody might kick him inside. But the athletic ability is what's intriguing to me. I think somebody will take him in the fifth round. He's a raw developmental guy that I think has starting traits."

Interior linemen

THE BEST

Name: Zack Martin

School: Notre Dame

Height, weight: 6-4, 308

40 time: 5.22

225 bench: 29 reps

Arms: 32-7/8 inches

Round projection: 1

Mike Mayock: "I think he's the only offensive lineman in this draft who could start at all five positions and play at a fairly high level at all of them. He might be a left tackle, but I think more teams are looking at him as an All-Pro center or guard. He started 52 games at left tackle at Notre Dame. Some teams think he could start at right tackle for a year or 2 and then get kicked inside. The beauty of him is, in a league where you dress only seven offensive linemen on Sunday, this kid can play every position. He'll be a top-15 pick."

THE RISER

Name: Joel Bitonio

School: Nevada

Height, weight: 6-4, 302

40 time: 4.97

225 bench: 22 reps

Arms: 33-7/8 inches

Round projection: 1-2

Mayock: "Another left tackle who probably will be kicked inside. He could survive at left or right tackle at the next level. He has good push at left tackle in the run game. But most teams are looking at him the same way they are Martin: Do you want a good tackle or an All-Pro guard? He's an immediate Day1 starter. I love this kid on tape. He played well against Florida State and UCLA. He's going to be a late first- or early second-round pick."

THE SLEEPER

Name: Spencer Long

School: Nebraska

Height, weight: 6-5, 320

40 time: 5.16

225 bench: 28 reps

Arms: 33-1/8 inches

Round projection: 5

Mayock: "He's coming off a midseason MCL tear. Played in just six games last year. He's a starting right guard in the league that somebody's going to get for value in plus or minus the fifth round just because he's coming off that knee injury and people aren't sure. But ultimately, he's got the quickness and the work habits to start on the right side in the NFL and he'll be great value."

Tomorrow: Wide receivers, tight ends
