personally, i would not do that. floyd is an injury risk as he has already shown.
are you worried that kevin brown won't last??? if so, you may want to do the deal. to me, vazquez has the same question marks (not quite as severe as brown, but questions nonetheless).
if you did it, you would be doing it for leiter over lawrence. that, i might do, but only do that trade. don't trade kearns for floyd and i wouldn't trade brown for vazquez.
i'd hold tight on this one. what about a closer?
