Theo and company may be working the lobby hard down at the Dolphin, but it seems our man Cash is “chilling in his suite” shuffling his iPod and not his roster. Andy Pettitte? Maybe. Melky or Pavano on the market? Not talking. A-Rod? Not on offer. Phil Hughes? Don’t even dream. Cairo and Bernie and Villone? We’re mulling….When it seems like nothing’s happening, that usually means something big is happening. But probably not.
