Colts - agree with HTatB above (too friggin long of a name to type)
They should take first if minimal injuries.
Titans - all depends on McNair. Knock him out, the Titans drop.
Texans - their position will depend on the above two. I would think about .500 ball this year.
Jags - defintely up and coming like the Texans. They're rebuilding in key positions as well. Will push the Titans and Texans and will do everything they can to stay out of the bottom.
