Pitt's Aaron Donald, whose lack of height has been an issue with numerous pro scouts, is the new No. 1 defensive tackle in NFL Media draft analyst Mike Mayock's updated position rankings.
Donald tore it up at the recent NFL Scouting Combine and had a strong pro day, as well. He was the No. 3 defensive tackle on Mayock's first list, but jumped two spots to bump Notre Dame nose tackle Louis Nix III out of the top spot. Indeed, Nix fell to No. 3, as Florida State's Timmy Jernigan remained No. 2 among defensive tackles. In addition, South Carolina's Kelcy Quarles moved into the No. 5 spot at the position, bumping Florida's Dominique Easley, who suffered a torn ACL in October and didn't compete at the combine.
There also is a new No. 1 offensive tackle, with Auburn's Greg Robinson moving up a spot and switching places with Texas A&M's Jake Matthews. Michigan's Taylor Lewan and Notre Dame's Zack Martin remained third and fourth at the position, respectively, with Nevada's Joel Bitonio moving in at No. 5 and bumping out Alabama's Cyrus Kouandjio.
There also was some movement at wide receiver. Clemson's Sammy Watkins remained No. 1, but Texas A&M's Mike Evans -- who ran better than expected at the combine -- moved up a spot to No. 2. USC's Marqise Lee dropped from second to third. Oregon State's Brandin Cooks, who was not in the original top 5, is now No. 4.
Washington's Bishop Sankey is the new No. 1 running back, moving up two spots after a solid combine. Ohio State's Carlos Hyde and LSU's Jeremy Hill dropped a spot each, and now are second and third, respectively.
