Carroll believes that Losman gives Seattle more depth and experience at the position, and also will make things more competitive for both Matt Hasselbeck and backup Charlie Whitehurst.
"He's got a terrific arm," Carroll said. "In his workout when we saw him, there was just no question that he had really good control of the football. His accuracy was there and he has fantastic strength in his arm.
"Our guys had evaluated him coming out (of college) and really liked him. We know that he's had a lot of play time that gives him some background. And we think he gives us a chance to be more competitive. And I already talked to Charlie about feeling the push from J.P., and that's how this goes."
What's not to like about adding a quarterback like Losman to the mix?
Losman, 29, washed out of the league in 2008 after five seasons in Buffalo. The confident, Southern California kid admitted to making his share of mistakes when Buffalo anointed him the quarterback of the future in his second season after releasing veteran Drew Bledsoe. But after two roller-coaster seasons in which injuries and poor play has Losman in and out of the lineup, Buffalo drafted Trent Edwards in 2007 and handed him the job a year later. That signaled the end of Losman's tenure. Losman demanded a trade at the end of 2007 after Edwards took over as the starter.
He finished his stay in Buffalo with a 10-23 record as a starter, throwing for over 6,200 yards with 33 touchdowns and 34 interceptions.
The Seahawks immediately put Losman to work, giving him some reps in team drills just a few days after signing him. As expected, Losman showed some rust. But he also showed off the arm strength that made him Buffalo's No. 22 overall pick in the 2004 draft.
For his part, Losman said he was just focused on getting comfortable with the offense on the field and getting the playbook down.
"The last thing to come is the sharpness and the pass efficiency," Losman said. "But right now you're just trying to complete some balls. But as the practice goes on very quickly here, you want to look a little bit sharper."
Carroll said the team is open to adding a fourth quarterback, and will wait and see how the evolution of the roster goes.
--The Seahawks continue to keep linebacker Leroy Hill away from the team's facility while he resolves his legal issues. Seahawks general manager John Schneider recently said the team expects to hear from the league about a possible suspension in the next, few weeks.
"We're really trying to rebuild this thing here," Schneider said. "We're waiting for the league and we're waiting for some of his legal things to be taken care of.
"When you're rebuilding things, you really don't want the distraction, so we just asked him to stay away for the time being, until he resolves some of these personal issues that he has going on."
Asked if Hill would be on the roster this season, Schneider said he's keeping an open mind and does not know for sure what the outcome will be.
"We won't know that for several weeks," he said.
With Hill not in attendance for offseason workouts, David Hawthorne has been filling the spot at weak side, outside backer. New linebackers coach Ken Norton Jr. considers Hawthorne a starter.
"He's extremely explosive, a big-play guy and a very good tackler," Norton said. "He's the type of guy that you can't hold back. You need him on the field. I don't even consider him a backup. He's a starter until someone unseats him."
--Carroll talked about his team's revolving-door roster this offseason. Since general manager John Schneider took over, the Seahawks have made 55 roster transactions, including five trades.
Half of the current roster was not on the team at this time a year ago.
Carroll said the constant roster movement is part of his overall philosophy of creating competition, and he does not think it takes away from the team developing cohesion as the regular season approaches.
"We think we have to remain open minded to the competitive aspect of bringing guys in here -- for one, to keep the message strong, and two, to keep looking to see if we can find somebody," he said.
"I think in a new program it's really important to do this, and so we're going to keep doing it. And there's no deadline when we're going to try and get everybody comfortable and settled. I don't think that's necessary here. Everybody here knows that this is a very competitive environment, and they're going to have to battle day in, day out. And that's the whole idea."
--Seahawks general manager John Schneider also addressed speculation that his team was interested in the services of veteran wide receiver Terrell Owens, confirming Seattle had made preliminary inquiries but now appears satisfied with the depth and overall talent at receiver.
"We're going to knock on every door," Schneider said. "His agent represents a number of our players, so we've had conversations regarding Terrell, but nothing substantial."
Schneider would not close the book on the team pursuing veteran wide receiver Terrell Owens, but he did say that the team probably would not move in that direction unless "something drastic happens."
QUOTE TO NOTE: "I think it's something I learned in baseball. We're always taught to catch the ball at its highest point. I'm catching a smaller ball, a little white ball in the air, so it's a little different. But I'm just trying to high-point the ball. I'm not the typical, 6-3, 6-4 guy, so I can't stay on the ground and expect to make a good play." -- Seahawks wide receiver Golden Tate on his ability to high-point balls over bigger defensive backs.
