From what I had read throughout the season, the Phillies wanted money and a good prospect, if not multiple prospects. I'd much rather get a starter, hell I'd rather have Cliff Lee than Papelbon, but if it's money and a decent/meh prospect then I'll be ok with it.
In other words if I woke up tomorrow reading a headline saying that we got Papelbon, my first reaction would be "oh crap, what did we just give up" rather than "yay we got a top closer to solve our bullpen problems"
