Ray Lewis is retiring to spend more time with his family. Matt Birk is still playing, in part, because of his.

The Baltimore Ravens center is 36, and he and his wife have six kids. When Birk contemplated retiring after last season, his family was supportive, knowing they'd have him around a lot more.

Then they saw what that would be like.

"In the offseason, I'll be home for a month or two and they'll be like, 'Isn't it time for you to go back to work?'" Birk said. "I like to try to get involved, and they have a rhythm at home. When we have the re-entry period in the offseason, where I'm home a lot more, there's always a few bumps."
