Tyler Lockett, Frank Clark among Seahawks poised to make second-year leap

The Seattle Seahawks drafted eight players in 2015, and six of them remain on the roster going into this year's training camp.

Below is a look at where those players (along with undrafted RB Thomas Rawls) stand going into their second seasons.

Tyler Lockett -- The speedy wide receiver caught 51 balls for 664 yards and six touchdowns as a rookie. He played 61.5 percent of the Seahawks' offensive snaps, and that number should be up in the 70s in 2016. Coach Pete Carroll said Lockett will be moved around a lot and "is in the middle" of everything the Seahawks have planned offensively. Lockett showed that he can win both outside and in the slot. He and QB Russell Wilson were just a tick off on several big plays downfield last season. Look for Lockett's yards per reception (13.02 in 2015) to jump. He's the pick here to lead the Seahawks in explosive plays.

Frank Clark -- He played 33.5 percent of the Seahawks' defensive snaps as a rookie and had three sacks. With Bruce Irvin now in Oakland, the coaching staff has pegged Clark to play right defensive end in subpackages. The Seahawks are counting on him to bolster a pass rush that features Michael Bennett and Cliff Avril. Clark is an elite athlete who has the ability to make plays behind the line of scrimmage and get after the quarterback. He'll now have the opportunity to be a difference-maker in the front seven.

Thomas Rawls -- As a rookie, Rawls piled up 830 yards and led the NFL with a yards-per-carry average of 5.65. What the coaches like most about Rawls is that he can make plays even when the blocking is not perfect. He averaged 2.68 yards after contact, the top mark in the NFL. The big question is Rawls' health. He suffered a fractured ankle in December that included ligament damage. The expectation is that Rawls will assume the role of the Seahawks' primary ball carrier and be ready for Week 1, but his health will be a storyline to monitor during training camp.

Mark Glowinski -- He started one game as a rookie but has been penciled in as the first-team left guard going into camp. Glowinski, a fourth-round pick in 2015, is a tremendous athlete who should give the Seahawks an upgrade on their offensive line.

Tye Smith -- Put him down as a sleeper who could surprise during training camp. The Seahawks like where Smith is at physically going into his second training camp, and he'll be competing for a spot at cornerback. The team has good depth at this position with Richard Sherman, Jeremy Lane, DeShawn Shead and Tharold Simon, but Smith will look to find a role in Year 2.

Terry Poole -- The Seahawks used a fourth-round pick on Poole last year, but he spent the season on the practice squad. He has the athletic traits the team covets in offensive linemen and will be competing for the swing tackle spot as a backup.

Kristjan Sokoli -- He played defensive tackle in college, but the Seahawks drafted him in the sixth round of 2015 with hopes of turning Sokoli into an offensive lineman. A superb athlete, he earned a spot on the 53-man roster last year, but he'll have to show he's making significant progress to stick for another season.
