If guys like Sosa don't get the chance to play through failure, they will never will succeed at the major league level.
If guys like Sosa and Colas aren't mentally ready for the majors in a basic sense, maybe we should look at who oversaw the system when they were supposed to be learning how to be ready for the majors in terms of baseball IQ.
If major league management can't teach these guys how to be major leaguers, maybe we should look at who is running the major league program.
If a steady stream of minor leaguers isn't good enough to even serve as a potential pieces for the future, maybe we should look at the drafting and development people.
You see how your excuses all have one common theme, right?
