SDS - I think the relevant point you made here is that although both Morgan and McCarver played for many years and were good at their respective positions, and their color commentary analysis about the finer points of the game is ok, the fact is when they start to quote rules is the time they need to shut up and go to a different topic.

It has nothing to do with playing, coaching , managing or teaching. They just never bothered to learn the rules the way umpires do. As far as either of them coaching is concerned, if they were that good they would be coaching now. Coaching isn't about knowledge and understanding - it's about taking that knowledge and imparting it to a player - verbalizing and/or demonstrating. Not everyone can do it, just like not everyone is cut out to be an umpire.
