We have a very big weekend ahead in the NFL and college football. Fortunately, we have a great group of guests to help us make sense of it all:

Gary Danielson: The CBS college football analyst will help preview this weekend's big games -- Alabama-Florida, Missouri-Oklahoma, USC-UCLA. And he should have some interesting insights into the recent coaching news around college football.

Jon Heyman: The SI baseball writer is on top of all the hot stove news. Find out the latest on CC Sabathia, Manny Ramirez and all the personnel moves teams are considering.

Tim Carr: The star and director of Leaf, a new film about Ryan Leaf, will join the show. We'll find out why Carr found Leaf so compelling.

David Feherty: The CBS golf analyst has some very interesting advice on how to cure back pain. We'll see how specific he gets, but knowing Feherty, he won't hold back.
