Looking for some advice. My son plays on an elite level club team at this age. He left one club team last season because they just didn't have the talent to develop the kids in a meaningful way. His old club has asked him to play for them at no cost this summer. There are no conflicts with his new club tournament schedule and it'll be 3 tournaments (his current coaches are aware and don't have any problems with it). He probably won't make any of the practices with his old team. He wants to do it because he still has friends on the old team. I want him to do it, because his new team has been running a lot of specialized D and O middies and he doesn't get to play much defense. His old team isn't there yet, so he'll get time out there on defense. Any reason to think it will hurt his development to be out there playing with his old team?
