Jack, I suspect JR had to be dragged kicking and screaming for that offer a few years ago. He doesn't like paying pitchers big money (to him, 100m plus is prolly big money).
The idea that the FO was gonna get him to agree to do that PLUS a big investment at either RF or 2B is not realistic.
If they want two big splashes they can probably buy one and trade Vaughn or some other big time youngster for the other. They aren't buying both.
