Before Pete Carroll can "Win Forever" with the Seahawks he has to worry about winning now.

And no other offseason move spoke more about the urgency to take advantage of momentum built last season than the trade for receiver Percy Harvin.

The Seahawks dealt three draft picks to Minnesota, including their 2013 first-rounder, for Harvin, and then signed him to a six-year, $67 million contract. That includes a scheduled $4.9 million in 2013, and then no less than $11.2 million in every season from 2014 through 2018.

"It's neat to know that you are wanted," Harvin said Monday, after completing his first organized team activity (OTA) with the Seahawks.

Harvin hadn't known if that was the case in Minnesota, where the Vikings weren't sure whether they wanted to make that kind of investment in him. In Minnesota, the narrative was that he was injury-prone, though he missed just 10 games in four seasons, and that he could be moody.

"He wears everybody out," one Minnesota columnist wrote in February when the debate was raging over whether the Vikings ought to re-sign him.

Monday, though, Harvin was the picture of contentment after his first official practice with the team.

"It felt good to finally get out here," he said. "It was great. I had a blast."

And while it's hard to read much from one workout without contact or pads, the Seahawks saw enough to make them think the trade might be worth it.

"His talent level is unbelievable, off the charts," said quarterback Russell Wilson. "He brings an explosive mentality to the game, which a lot of our guys already have. But to have him is truly tremendous. He's a guy that's been one of the best football players in the National Football League for the past several years."

Harvin, 24, has averaged 1,800 total yards in four seasons and was on pace for 2,400 yards in 2012 — which would have led the NFL — before an ankle injury ended his season.

In those nine games, he had 62 catches — 12 more than any Seahawk — for 677 yards. He also had 96 yards rushing and 574 yards on kickoff returns, including a 105-yard touchdown return.

The Seahawks plan to use him similarly. He'll likely line up in the slot as his regular spot, but figures to get used outside, as well, and should see his share of handoffs and kickoff returns.

"I'll be moving around — pretty much all around," said the 5-foot-11, 184-pound Harvin. "There'll be a little bit of running back coming up. But right now, we're just trying to get the foundation set, just running the base plays, and we'll see where it goes from there."
