My buddy and I are forming a 10u select team for next fall (only) and looks like we may have found catcher #2 already. Both of our DDs pitch, and we've got a third pitcher who will get plenty of innings. Six players are already guaranteed spots.
This is the usual formula for how Daddyball teams are formed at 12U and particularly at 14U (ie both coaches DD's pitch, already have guaranteed spots for half the team, blah blah blah).
However, nanotech, I'm on the fence about calling it Daddyball at 10U because you do need to start somewhere, and unless you are part of an established organization, how else do you do it? It is usually the pitchers' dads that end up starting teams at younger ages - have you ever seen a non-pitcher's dad start a new team? I'm sure it happens but I have not seen it yet.
