I partly agree, but if they get through 6 innings, I don't think they use the middle or long reliever.  I also think Dunn may be turning it around.  It seems McGee has been the primary setup guy for July, but I don't know if that was a demotion or giving Dunn more time post DL.  He only pitched 6.1 innings in July, but that produced only one hit.  

Anyway, the point is they need middle/long arm for about 3-4 innings when the starter implodes.  The offense has been spectacular, but they still haven't completely won me over on comebacks.  That's when you see guys swinging on pitches that are almost wild, lol.
