As the Seahawks began to break out offensively in the second half of the 2012 season, so did receiver Golden Tate. During Seattle’s 7-1 finishing kick that marked the Seahawks as a legit Super Bowl contender, Tate finally began to become the player the Seahawks suspected he could be when they took him in the second round of the 2010 draft. Tate led all Seattle receivers in the last nine games with 32 catches for 497 yards and four touchdowns, appearing to forge a solid chemistry with quarterback Russell Wilson. He finished with a career-high 45 receptions for the season. He then had another 10 catches in Seattle’s two playoff games. All of that sent Tate into the offseason with happy visions of an even bigger step forward in 2013, a year that looms critical to his future as the initial four-year contract he signed with the Seahawks expires at the end of the season. So Tate admits he initially cast a somewhat quizzical eye when the Seahawks, under the direction of coach Pete Carroll and general manager John Schneider, acquired receiver Percy Harvin from Minnesota in April. “When I first heard, I hadn’t spoken to any of the coaching staff or the (general manager) or the owner or anybody, so I didn’t really know what to think at that time,’’ Tate said. “But shortly after, speaking to Pete and John, they explained it to me that it shouldn’t affect me much.’’ Carroll said he understood Tate’s first reaction. “Initially Golden wondered, ‘OK, what does that mean to me?’ ’’ Carroll said. “He was concerned about that. A number of the players were.’’ The recently concluded three-week set of 10 organized training activities, though, helped further calm any concerns Tate had about how he and the rest of the receivers will coexist with Harvin. Harvin primarily will line up as an inside, or slot, receiver while Tate is primarily outside, a spot he played most of last season after the team stopped with its experiment of 2011 to make him more of an inside receiver. With Sidney Rice also primarily an outside receiver, the Seahawks could go with a lot more three-receiver sets this season. “I’m excited about it,’’ Tate said. “I like the way the offense is playing out to use him. ... I’m excited to see how creative our offensive coordinators and receivers and coaches can get.’’ Carroll says there shouldn’t be an issue finding enough touches for all of the receivers. “We’re not counting on tilting the field toward one guy or the other,’’ he said. “I’m not thinking that way. We’re just going to go play football. “Golden is really ready to be a terrific football player. We love what he does, and we just have to get him the ball more and spread it around to him. It took him a couple years to get going and now he’s legit for us and we love what he brings. And he does different things than what Percy does. Percy is a very unique quality guy. I think it’s going to fit together just fine.” And Tate insists the fact that his contract is up after this season isn’t weighing heavily on his mind, even though he might have as much individually on the line this season as any Seahawk.
