Recently acquired running back Michael Robinson will face his old teammates on Sunday when the Seahawks take on the division rival 49ers at Qwest Field.

"It's fun," said Robinson. "I love those guys. I have nothing bad to say about them. I made some of my best friends on that team. But at the same time, it's football, it's a competition."

"I think that's the whole part of the NFL, you could be on this team one week and on another rival team the next week. That's fun."

Robinson is one of 180 personnel changes on the Seahawks' roster since Pete Carroll and John Schneider came to town.

So in the spirit of competition, is Robinson giving his new teammates a lesson in the 49ers?

"I don't have to tell these guys much," he said. "Most of these guys have played the 49ers two times a year anyway, so they know. That's part of being a professional, that's part of knowing. Because in the NFL you can know what a team is doing, and you still have to go out there and play and stop it. So it really doesn't matter."

Robinson brings a comprehensive skill set to Seattle, having played quarterback in college before the transition to running back. Robinson was named as a special teams alternate in the NFL Pro Bowl the last two seasons.

Asked what he believes he does best, Robinson replied: "I don't know. I try to do everything great. That's just my mentality that has been instilled in me since I was a little boy. I try to be the best at everything I do. Whatever the team asks me to do that week I'm going to practice as hard as I possibly can to be the best at that position, that particular week."

For now, Robinson is going to focus on helping his new team to win from the start.

"We're in the NFL," he said. "Everybody is big, strong, and fast. But they're no bigger, stronger, or faster than we are. So we just have to go out and play football and see where the chips fall."
