Jets coach Rex Ryan says no one should expect Percy Harvin to become the team’s best offensive playmaker instantly.

Ryan says Harvin will have a role in the offense on Sunday against the Bills, but no one should expect him to know the whole playbook after a week with the team.

“I’m just saying that it’s hard to expect a guy to come in and learn an entire offense,” Ryan said. “We’re going to use him. It’s not to expect him to play 50 plays or something like that. That’s probably unrealistic.”

Ryan said the Jets may use Harvin on both kickoff returns and punt returns, even though Harvin has never returned a punt in the NFL or in college. For Ryan, the goal is just to find the best ways to use Harvin.

“I think when you look at how we are going to use Percy, it might be different than how he was used in Minnesota [and] how he was used in Seattle. I guess time will tell, but I truly believe with his kind of talent it’s going to be a big help, obviously for our offense and with that, our whole team,” Ryan said.

If the Jets can go on a run in the second half of the season, big plays from Harvin may contribute to saving Ryan’s job.
