I'm on the other side of this one. HS coaches spend a WHOLE bunch of hours with the kids. IMO, if we are JUST teaching baseball skills, we are missing out on countless opportunities to teach and reinforce other life lessons and the importance of player character.
As far as specific methodology, that will be different with each coach. If the spirit or intent of the lesson is positive and the message resonates, then good for the coach. In this case, all I'm hearing is some are being rewarded for hard work and some are being given a carrot to improve.
Yes, the uniform should be the same for each. But a leather belt instead of elastic is identical looking, just symbolic. To me, this is similar to a player or two wearing the captain's "C" on their uni (granted, not as common in baseball, but you get the idea).
Yes, a coach should demand hard work from all. But, rarely do you have a team that has equally hard working kids throughout the entire roster. This is just one coach's attempt to cultivate more.
Our staff attacks from all angles... sometimes nurturing, sometimes pushing hard, sometimes praising, sometimes scolding, sometimes individually, sometimes as a group... for both baseball and for character traits. Isn't that a good thing?
PS - Well, my slow typing fingers... I see Goosegg and Shoveit beat me to the same thought process.
