I vehemently disagree. He is more in line with a 70 OFV that still puts superstar in his range of outcomes. In addition he has a profile that is not likely to bust completely. Of course no one knows if he will ever reach his true ceiling, but he is likely to have some value for a big league club for the foreseeable future just based on his tools alone. To trade that away for anything less than a cost controlled, young superstar would be foolishness. The list is Griffin, Wood, McGonigle, Caminero, Kurtz, and possibly Skenes and McLean. (Almost all of which were top 5 prospects in the game with a similar FV) I think you are heavily discounting his ability and production relative to his age. Which is fine everyone is entitled to their opinion.
Fact is the Brewers are only gonna have a superstar through scouting and development. They're most likely not getting one in a trade, and certainly not getting one in FA. Made is their best chance at that and I am hesitant to trade that away for a very good player. When in reality it's decently likely Made becomes a very good player himself with ceiling to grow.
