One way to do the whole leave the team/tryout thing is to:
a) make it pretty clear on DFP that your kid is leaving and have it filter back to the org so that
b) at the end of the season the coach puts out an ad looking for your kids' position before any in-person discussion has been initiated but then
c) messages you after the ad has been put out saying he would love to have your kid back but only if you stopped saying mean words about him (even though he is never actually named ) on DFP
Not that I know of that happening to anybody but I figured I would just throw it out there....
Well, jees, that happens so often it should just be common sense by now
