Usually, but I bet the Giants FO think they really have to show something for this trade to the "regular" fan. I wouldn't be surprised if the Giants pay most of the MadBum contract or package him with some other prospect(s) to get that much better a prospect(s) back. This trade will be under the microscope, so they will probably want somebody close to major league ready. Perhaps. The Tigers traded Verlander to the Astros for three very young, far off prospects in 2017 . Granted all three were considered very good prospects, but they were very young. Franklin Perez was the crown jewel of that deal, and after scuffling pretty much all of last year, he is pitching well at the A+ level as a 21-year-old. Daz Cameron is off to a middling start in AAA this year as a 22 year old. Jake Rogers was the oldest of the three at 22 when dealt, and he started this season at AA as a 24 year old, and was moved up to AAA pretty quickly. He's playing well. But Verlander, who had just as much of a history as MadBum, and had 2 1/2 seasons of control to boot, was traded for three prospects who, while exciting, were so far away from being major leaguers that it is 1 1/2 seasons later and none have had any ML time yet. Every team is going to want to trade their players for ML-ready studs, but those type of prospects are rarely dealt. Most of the time it is high upside these teams are getting back. The Brewers don't have a ton of prospects that are close to ML ready, but they do have a fair number of high upside guys that the lower levels that could theoretically be used as trade currency.
