As for the the way the MLB teams are "coached", it's already been said that watching big league players for cues on how things should be done at a fundamental level is largely a mistake. When they do things fundamentally sound, it's b/c they want to. Not b/c they fear what a coach may say or do to them.
I've spent enough time around very high level baseball coaches, where skills are still taught, to know that catching fly balls one handed is frowned upon. I don't think the examples of smaller gloves, past great hitters, and professional golfers need any more explaining. I guess I could throw in the example of scoring positions in lacrosse using shorter sticks than those of defensive positions.
Superstar players may get away with ignoring instructions from their coaches, but most players are required to do exactly as they are told.
Catching with two hands is no longer considered a good way to field a ball and hasn't been for decades and even before that it wasn't the standard at upper levels. Choking up is something that a few players do, but most do not. Very few hitting coaches would instruct their players to choke up. It is an obsolete approach because it simply doesn't help in the way people used to think it did. If it worked it would be commonplace.
