As AndyB said, we also could use a #2. Hey, it isn't as if there is no prior history for this. We traded for both Lee and Halladay We didn't trade anyone of Moniak pedigree in either of those deals. The key thing about Galvis and Rupp: they are not untested prospects. They are major leaguers coming off plus seasons. That has great value, for a GM who wants to say he's gotten some immediate help, but also wants cheap and controllable. Perhaps a third guy (a prospect) will have to be included. I'd include Williams if the deal got us a #1/2 in return. I think that deal lines up quite well with what we gave for Halladay or Lee.
A deal like Lee/Halladay isn't often available. It's easier to work such a deal when a team needs to dump salary at a time when most teams are unable to take on salary. We had to unload Lee, fairly cheaply, in order to clear salary to sign Halladay. I am by no means saying a deal such as the one I outlined above is available today or early in the off-season. You need to be ready to spend money, make trades, and add talent at any time, because these deals do become available, sometimes when you are least expecting it, and you can't say 'too soon, I'm not going to spend the big $ or trade young players, until my team has at least 85 wins.' Opportunity doesn't come knocking every day and ignoring it because of some hard and fast rule --- well, IMHO it would be silly.
