After doing 'Firefly' and moving on, I always wanted to be part of a series again. I love doing films, too, but there's just something special about being part of the team and feeling like you're actually a part of the family, and I always look to re-create that.
But when you get into a situation where you can acquire a proven leader, a proven quality player, an unselfish player, a guy who taken a team to the Super Bowl, I think you do it.
When you're in shape, you don't have to walk up to somebody and say, 'Yo, I love myself.' You look like you care for yourself.
