Loyalty is a two way street. I absolutely expect my kids to be loyal to me during my season. Once my season is over it's their time. Do I want them to play for me this summer? It depends on if the level of play my summer team provides is what they need and for my varsity guys it's usually not. My summer talent is usually closer to JV level baseball - which I'm totally fine with because I use that time to help them get better. But my varsity guys need to play at a higher level to get better but also increase their chances at going to the next level.
Times change and the old American Legion guys just want to keep their dream from back in the day alive.
