I don't usually play fantasy point leagues (I'm strictly a roto guy at this point) so I'm not sure if strategically this makes sense for you... but I'd seriously look into getting another closer for the "P" spot. Other than that, your pitching doesn't look shaky at all to me. Perez is obvious weak point, but he's only your 4th or 5th starter, which gives you plenty of time to figure out what kind of year he'll have. I have absolutely no hesitations about Bedard at this point. I would have liked him as my staff ace; to have him as your #2 or #3 (depending on how much you like C. Young) is absolute gravy smooth.
