No, they aren't, unless they think he's still going to be as productive in 2020. They are, more likely than not, trading for Braun's production over the next year or two and are fully aware he probably won't be the same player in 2020. Who should pay for 2020 Braun may well be why he hasn't been traded. That part can be negotiated. But production 4 years down the line is not what teams are trading for. So in a way it doesn't really matter what his WAR will be 2020. That is the problem though. They don't want to trade for 2020 Braun...but they would have to. Unless you think the Brewers would pick up that much money, but I really doubt it. Not to mention it sounds like most teams wish it was 2 years after this...not 4. So that is a near $40mil problem.
