One of the fastest-rising Nick Chubb Jersey prospects leading up to last year's draft was Pittsburgh defensive tackle . This season, one of the fastest-risers has been Pitt offensive tackle . Interestingly, the two once lined up together on the defensive line. Clemmings (6-foot-5, 307 pounds) spent his first three seasons at Pitt (including his redshirt year) as a defensive lineman. He was moved to the other side of the ball in 2013 and did a solid job at right tackle. He did an even better job at right tackle this season, and now he looks to be a first-round lock.It seems as if he could be changing positions again, this time to left tackle. NFL Media analyst Mike Mayock raved about Clemmings on NFL Network's coverage of the Reese's practices, saying that Clemmings' "physical traits are all left tackle.""I believe at the end of the day, if things play out, he'll be a top-10 pick," Mayock said. "He's got beautiful feet. He's a dancing bear. He's a guy that's a pa s protector first. He just needs to clean up technique and get stronger, especially in his core areas."In their first mock drafts, NFL Media analysts Daniel Jeremiah and Bucky Brooks had Clemmings just outside the top 10 -- Jeremiah had Clemmings going , and Ogbo Okoronkwo Jersey Brooks had him going .As for college right tackles making a smooth move to the left side, fellow Jalen Camp Jersey analyst Charles Davis pointed to , who played on the right side at USC but was drafted in the first round to play the left side with the . Smith was an All-Pro this season. Some other observations about offensive linemen from NFL Media analysts: Mayock praised Duke guard (6-3, 323), who might be the first player at his position taken in the draft. "He's a starting guard in the NFL all day long," Mayock said. He also said Tomlinson is a "road grader in the running game. And he's a better pa s protector than people think." Duke hasn't had a player selected earlier than the fourth round since 1999; Tomlinson should change that this year. (6-4, 307) played left tackle for Arizona State this season and was an All-Pac-12 selection. But he previously played guard for the Sun Devils, and Davis said "Douglas' future is inside at guard." Penn State's (6-6, 341) was a three-year starter for the Nittany , and though he has graduated, he left school with one season of Jowon Briggs Jersey eligibility remaining. His decision to turn pro , including Mayock. But Mayock also thinks Smith has an upside: "This kid can be a better football player than people understand." Daniel Jeremiah said Smith's size obviously is appealing and that "he moves people in Ray-Ray Armstrong Jersey the running game." Smith is one of the more mysterious tackle prospects; he looks to be a third-day selection, but perhaps could move up some draft boards. Hobart (N.Y.) is a Division III school, and tackle (6-4, 307) is the only D-III player in the game. Mayock said that while Marpet is raw, he remains intriguing. "What would really help is if he can play all three interior line positions," he said, noting that Marpet could begin his NFL career on a practice squad.
