I agree. They had better get a king's ransom for Donaldson though. At least four high end prospects.
So I did some thinking about this, to try and come up with a player who was similar in value to Donaldson who got dealt so as to gauge what he might fetch in a trade. I don't know that I came up with anything perfect but three deals came to mind that maybe give us a framework.
The first one was Chris Sale, probably because it's the most recent. Sale was a legit, #1 ace kind of guy traded in his prime and the White Sox got a pretty hefty return. They got one of the consensus top 10 prospects in baseball(Moncada), another top 100 guy(Michael Kopech) and then two lesser prospects.
That's not a great comp though. Sale is younger, has more team control and isn't actually as valuable on the field as Donaldson's been(19.5 bwar in his three best pre-trade years to Donaldson's 24.0). I also think teams tend to overpay for pitching.
So then I thought about Miguel Cabrera. That's a little more complicated though for a few reasons. Cabrera was significantly younger(25 to 31), Cabrera's value was artificially lower because he was playing out of position and the deal wasn't just for Cabrera but also had some salary throw-ins. Anyways, the structure's not all that different. Cabrera went for a consensus top 10 prospect(Cameron Maybin), a consensus top 20 prospect(Andrew Miller) and then a couple other guys who could generously be called B or B- prospects. But again, that was a weirder, bigger trade.
So then I thought, maybe the best comp for Donaldson is Donaldson? True, Donaldson didn't have an MVP and the eye-popping stats when Oakland traded him but his value in his two best Oakland years(15 bwar) wasn't much lower than his two best Jays years(16.3 bWAR).
Anyways, when the Jays traded for Donaldson then they maybe got something closer to your idea of four high value guys although they didn't get the top end talent Chicago or the Marlins did in their deals. The Jays traded a top 100 guy in Barreto, a fringe-y top 100 guy in Nolin, a good prospect in Graveman and then whatever we want to call Brett Lawrie(a good ball player but someone who'd stalled a little and struggled with injuries).
So there's no great comps. My guess though, and this is just a guess, is that if you trade Donaldson you'll probably get something similar to what Sale and Cabrera got but with maybe less high end value. So maybe a top 20 prospect, another top 100ish guy and then a B- sort of guy.
