Yes, they'll win. Unless you mean win a world series, in which case, they wouldn't be on the top of my list for that. But anything can happen, I guess...
I can safely predict the Cubs are not gonna lose all 162 games this year, so yes, they're gonna win this year. By the way, they're not winning the World Series.
Not a chance, sadly. Marlon Byrd was hardly worth the money they spend and they let Rich Harden walk out the door. They need pitching and they don't have it.
