We won't sign anyone.
If Manning or Manning&Wayne fails, obviously we'll look at QBs, but until then I don't think we waste cap space till the Manning situation is done.
Even then, I'd be surprised if we get in more than one FA. Philbin has said in no uncertain terms that he is not a believer in building through FA. He's probably a bit p'eed off that signing Manning is being foisted on him (that's not to say he doesn't want Manning, more that it's not his choice). So I think he'll be very limited in FA, if he buys at all, to demonstrate that he wants to build the team according to his principles.
