It was about the only sign of just how much Seattle's starting cornerback might be looking to this week's matchup against Lions wide receiver Calvin Johnson, who is known by the nickname "Megatron."

For anyone who needs a Transformers refresher course: Optimus Prime was the leader of the good-guy Autobots, Megatron the leader of the bad-guy Decepticons.

When asked about matching up against Johnson, though, Sherman played it cool.

"Same challenge as every week," he said.

"I don't care who's out there. It's the league, boy, they're going to have a good receiver out there every week where it's Fitz (Larry Fitzgerald), Steve Smith, you've got Brandon Lloyd. No different. It's good receivers."

But maybe Sherman is looking forward to this one, right? After all, Johnson did lead the league with 1,681 yards receiving last year.

"I look forward every week," Sherman said. "Get my hands on someone."

Well, how about facing a receiver who's 6 feet 5 like Johnson? What does that mean?

"Nothing to someone who's 6-3," Sherman said. "Actually, it might be a little less of an issue due to height. Closer to size, you move similar to him. It's better than the small little guys, who you don't move the same as. He's got a long stride, I've got a long stride."
