Yep - and I would have made him the entire lynchpin of how to determine the best way to sell. The reason I say "lynchpin" is MAYBE we could have gotten a couple of actual interesting prospects if we'd paid his whole salary, and if that was the case, I'd have advocated that. But obviously nobody knows this for sure.The question of whether they could have given JD away for free is basically the most central to the whole buy/sell/hybrid debate.
It's 100% fine to say they should have sold, as long as one has realistic expectations of what that would look like in terms of return.
I assume someone would have taken a shot on him for a bag of baseballs to take on his salary, which I think would have been worth it because I think you'd have gotten the same deal (at worst) for guys like Wacha, Hill and Strahm, injures or not.
Most realistically, I think we could have gotten something approaching "Clayton Beeter" in value for JD Martinez (that's what the Dodgers gave up for Gallo). Something along the lines of Mickey Moniak for Wacha (the Phillies gave up he and Jadiel Sahchez), and maybe something like Sawyer Gipson-Long for Strahm (what Detroit got for Fulmer), but more importantly we would get another $800k in draft slot money and two slightly better shots at decent players from the comp picks for Eovaldi and Bogaerts.
