Before the signing of Looper, I can remember having an extended discussion here about the quality/durability of the rotation as it then stood (Gallardo, Manny, Bush, Suppan, and maybe McClung or Villy). I, for one, refused to believe that all five of those guys were going to come close to making 30+ starts each -- it seemed totally implausible. The acquisition of Looper mitigated that problem somewhat, but, even then, you were were looking at (roughly) the five above + Looper each having to make 25 starts each -- which, at least to me, still seemed implausible way back in April. The fact that the team is now scrambling to grapple with this rotation depth problem (in the persons of Mike Burns and Vargas) frustrates me because it was foreseeable before the season even began.
