I've named several trades in the past, but the problem is, we can never be sure the other teams would say yes.
Take the Kimbrel deal, last winter I suggested we sign Clippard and make a minor trade for KRod. I also said I'd rather have signed Miller than pay more (per year) for Kimbrel. Assuming those possibilities, maybe even combined, were possible, then I'd have offered a mega deal to sign Carrasco, Salazar, Quintana or Sale, but again, those guys were probably not available unless there was a massive overpay. I thought I was offering an overpay, but we'll never know, if it was "massive" enough. I did not include Espi in the deal, but now that he has been traded, one could consider the chances with him added to a deal.
I offered Swihart, Margot, Guerra (still had high value then), Owens & Johnson (both had higher value last winter). Sub Espi for Owens and Johnson and I think we get someone to listen.
Looking at trades made recently, and trying to figure out if we could have offered more is also a difficult thing to do, but I think we could have gotten Matt Moore for less than Espi, Margot, Guerra and Allen...way less.
Right now, I'd have offered Swihart, Margot, Allen and Espi for Quintana, and had we signed Miller, we'd have Quintana-Miller, instead of Pomeranz-Kimbrel (minus Swihart). I realize this is jusr speculation, and I know I'll be accused of beating a dead horse, but we gave up top talent for the right to pay FA like money for a closer and a mid-rotation starter with a very little record of success. I know, it sounds like Monday morning quarterbacking to always say this and that deal suck, but I have offered alternative suggestions that are more times than not criticized for offering too much- not too little.
