I think they will eventually, but they will probably be a lot more stingy about it. I think they're serious about their "build from within, complement from outside" philosophy. If Stanton was a FA, they'd be all over him, but the $$$ + prospects combination is very rich.
To be honest, i think Choo is more up their alley and would not be surprised to see them sign him if Boras drops those ridiculous demands.
