With all do respect, I think your valuation of Kloffenstein and Robberse is off.
Kloff won't provide any major league value, or I'd be shocked if he did.
Robberse I think will pitch in the majors but either as a #5 or a long reliever. He might give you some valuable innings over his career but nothing to lose sleep over. An easily replaceable arm.
I think Hicks gives this team precisely the swing and miss stuff they've been missing come playoff time.
I guess time will tell how this all plays out though.
