Harvin played in the divisional-round playoff game against New Orleans, but suffered a concussion.
“It’s been weird,” Harvin said. “It’s been frustrating. It’s been all the above, man. I had a tough time, and it wore on me a little bit.”
Harvin plans to blend into the Seahawks’ attack.
“I’m just adding another playmaker,” Harvin said. “We already have three or four good receivers out there. I’m just adding to the mix. We just think with all of us collectively on the field together, along with them trying to stop the ‘Beast Mode’ (running back Marshawn Lynch), we just feel collectively that it will be a tough time on defense.”
