That's a brave approach!! Yes, your players get complete experience at 1 position and can get very good at it as opposed to dividing the experience between 2-3 players. It also makes for easy line-ups before the games. BUT, you need to have about 6 sets of EXCELLENT parents who aren't going to mind paying $400-$1000 for their kid to NEVER get a shot at the infield. You also have to pray to the good lord above that you never have an injury. By the sound of it, your infield does NOT adjust well if you don't have all the "starting infield" in, so you may be in big trouble if one of your infielders gets hurt. Players get hurt all the time at home, school, or the ball fields. They have weddings, funerals, graduations, or the Chicken Pox. There will come a time when all your players are not available, and if you don't prepare for it, it will bite you hard!! Not to mention you are left with a team of 1 dimensional players. If those players move onto a different team for whatever reason, they will only have learned 1 position the whole year. I know as a coach, I like my players to be more versitile. I want to know that they are capable of learning and playing more than 1 position. It makes them more rounded and they can understand the game better if they see it from more than one point of view. Our job as coaches is to develop well-rounded players, not win every game.
