And don't forget Boston had a surplus of pitching when BA was acquired. That early Cy Young canidate was slated for the bullpen so it wasn't like it was going to take much to pry him away. And the market for pitching reliefe and starting both, has done nothing but go up since.
I don't have a problem with trying to get an under-the-radar pitcher, in fact I think that's the route they should take (or have taken). My only point was that even had we hung on to them we'd still be having to overpay in cash/trade to get what we need. You either overpay then, or overpay now.
