DE Bruce Irvin

First round, No. 15 overall

Irvin is backing up Chris Clemons at the LEO defensive end position, and also part of the team's nickel pass-rush package, which currently consists of Clinton McDonald and Jason Jones as the defensive tackles and Irvin and Clemons as the ends. Watching him rush off the edge is pretty impressive as he's explosive coming around the edge, and it was impossible to miss his speed as he ran down running back Marshawn Lynch from behind in Sunday's scrimmage.

MLB Bobby Wagner

Second round, No. 47 overall

He worked extensively with the first-unit defense at middle linebacker until a thigh bruise kept him out of practice the last three days. While coach Pete Carroll has held off declaring him the starter at middle linebacker, the Seahawks are clearly getting him ready to be in that position with veteran Barrett Ruud providing backup. The fact that strongside linebacker K.J. Wright can call the defense with Wagner echoing the calls at the line is further evidence Seattle is preparing to start the rookie.

QB Russell Wilson

Third round, No. 75 overall

Wilson is part of Seattle's competition to determine a starting quarterback, and so far he has had two days of practice working with the first-unit offense. He's got a big arm, and his ability to throw the ball deep is clearly a strength. He also can improvise as he showed on the second day of training camp, rolling out of the pocket on a scramble before heaving the ball downfield to Ben Obomanu. The danger sign for Wilson is that he has shown a tendency to overthrow receivers at times, the ball sailing up and over his target, which is a strict no-no for a quarterback.

RB Robert Turbin

Fourth round, No. 106 overall

His biceps are every bit as big as advertised, but he's not a plodder or a bruiser. He's got a lean lower body, and is faster than you would expect based on his upper-body physique. He's still adjusting to running in Seattle's one cut and go, zone-blocking scheme but so far line coach Tom Cable likes what he's seeing. In Saturday's practice, Turbin had a play where he hesitated making his cut. Cable corrected him and three plays later broke off a big run, earning an echo of compliments from Cable. "He kind of went in there, and he pitter-pattered," Cable said. "Kind of stomping snakes. You can't do that in this system, and in this league because you're going to get hit about 18 times. That next time he got it, he made one cut and ripped it through there clean. You've got to tell them right then, 'That's it.' When they get it, you've got to capture it."

DT Jaye Howard

Fourth round, No. 114 overall

Howard is someone the Seahawks think will provide a pass rush from the interior tackle position. The fact that Jones has been so impressive in camp that coach Pete Carroll says he expects Jones' diet of plays to be heavier than the team initially projected when it signed him. Could that cut into Howard's opportunities?

LB Korey Toomer

Fifth round, No. 154 overall

Very athletic linebacker who moves very well, but so far in training camp, Mike Morgan has been working with the second-unit defense at strongside linebacker. K.J. Wright is the starter at that position.

CB Jeremy Lane

Sixth round, No. 172 overall

He's a feisty player, who was ejected from Sunday's scrimmage as coach Pete Carroll sought to make a point about fighting. He's someone who has experience playing against the slot receiver in the nickel defense, a spot where Roy Lewis has played the past few years and where Marcus Trufant is a consideration.

S Winston Guy

Sixth round, No. 181 overall

He played four different positions in college, and it looks like he'll have a role right away in Seattle's defense in the Seahawks' Bandit package, which puts six defensive backs on the field at the same time.

G J.R. Sweezy

Seventh round, No. 225 overall

A defensive lineman in college at North Carolina State, Sweezy is making the transition to offensive guard and doing it quite fast. He worked with the first-unit line during Sunday's scrimmage, and while that shouldn't be mistaken for a sign he might start, it is a signal that he's adjusting well to playing on the offensive side of the ball.

DE Greg Scruggs

Seventh round, No. 232 overall

The Seahawks are looking at him inside as well as outside, but Seattle's depth along the defensive line will make it tough for him to start the season on the 53-man roster.
