I'd slot Belisle 4 and Volquez 5. Belisle can be the "take one for the team" guy allowing Volquez to be babied a little (not needed as much for him at his age as it is for Cueto IMO) with Harang following him.
Fogg is the long reliever that can come in and save the pen so that a bad start today doesn't have to mean pitcher abuse tomorrow. Fogg can also take a turn once in a while to allow the team to push everyone back a day or to allow one of the guys who may be gassed to skip a spot once through the rotation. I think that would set up quite well. Affeldt goes back to being a 1 inning lefty and hopefully fills a huge hole on this team. Bailey gets his 160 inning season of command development in AAA which should allow him to be an asset in 2009.
Fogg spot starting and long relief.
Best rotation since the late 80's, maybe longer.
