Are you serious? Maybe you're talking specifically about guys close to joining the MLB squad, but otherwise Rafael Devers, Javi Guerra and Mauricio Dubon are demolishing minor league pitching in the lower rungs of the org.
Look, it's hard to take you seriously when you say in one breath that you "don't understand or care how valuations work" then turn around and say "you don't see any kids demolishing anything". If you don't understand or care to understand how valuations work, your opinion comes off as arrogant and of little value.
As for JBJ, all he can do is keep hitting. They will give him another chance, but if he sucks again, his next chance may be in another org.
