I think Philly, San Fran, and Tampa are the best.
I would add to your list of honorable mentions with The Dodgers for Kershaw and Billingsley alone (though they don't really have much after that - Aaron Harang is probably past his best years); The Marlins for Josh Johnson, Mark Buerhle, and Ricky Nolasco; and maybe the Rangers - even though they lost C.J. Wilson, I think Yu Darvish could make the rotation better than last year's version.
