Harvin made an impact in his Seahawks debut during Sunday's 41-20 win over the Minnesota Vikings, finishing with a 17-yard reception in his lone target and setting up a touchdown drive with a 58-yard kickoff return. He played 20 of 54 snaps.
Carroll told reporters Monday that, barring a setback, Harvin will "be in normal rotation and returning kicks and the whole thing" when the Seahawks return from their bye in Week 13 against the New Orleans Saints. Harvin will have to find his niche in the offense, however.
"We don't have to hold back and count plays and stuff like that. He'll play a regular amount as we go," Carroll said, via ProFootballTalk. "He won't play every play; we're going to still rotate our guys. We're not changing the offense.
"I told Percy that the first night I talked to him. I told him we're not going to change because you're coming to our team, we're just going to add you in and hope you can be a factor to help us, which he's going to be."
If healthy, Harvin is going to find his place in this offense. He's the most talented wide receiver on Seattle's roster and figures to be quarterback Russell Wilson's favorite target down the stretch. It's a scary thought for the other Super Bowl contenders, but Harvin makes the Seahawks a lot better.
