Tyler Lockett is eye-popping quick: The third-round wide receiver pick from Kansas State was one of the standouts because his quickness off the line of scrimmage is so obvious. On one play Friday, Lockett was lined up outside against a corner who was trying to use press coverage against him. Lockett took two quick juke steps and ran right by him like he wasn’t even there. Lockett, who also had a long TD catch Sunday when he ran by the defenders, easily gets separation on pass routes. But let’s be real: Most of these guys won’t be here next week. Nevertheless, Lockett was impressive as a receiver, though his main job this season will be returning punts and kicks, a huge area of need for the Seahawks.

Kristjan Sokoli has a lot to learn: The Seahawks made the University of Buffalo nose tackle a sixth-round pick and are moving him to center, a position he has never played. It shows. At one point Saturday, Sokoli had four consecutive issues with snaps, two in the shotgun and two under center. But that’s to be expected and just part of the process. Seahawks coach Pete Carroll knows it will take time, but Sokoli shows all the movement and quickness they were hoping to see.

Eric Pinkins has moved to outside linebacker: The Seahawks made Pinkins a sixth-round draft pick last year as a safety out of San Diego State. They tried to move him to cornerback to see if he could be a big, physical corner like Richard Sherman. But Pinkins suffered a Lisfranc foot fracture and was on injured reserve all last season. He is 6-foot-2 and weighed 220 pounds last year; now he’s up to 230. The coaches want to see how he handles the Sam linebacker spot because Pinkins is a strong tackler with excellent speed. He looked comfortable in that role in rookie camp, but there’s no actual tackling so it’s hard to know how he might do at this point.
