And the above posts make clear that so much of this is about who gets showcased and when. When daddy is coaching, his kid (and the kids of his buddies) get showcased and are then seen as the better kids. If a kid is not on the field as much he cannot impress and, more importantly, isn't improving as fast. Take a kid put him as a first line middie and also on your man-up team. Then take the same kid off man-up and put him on the third middie line...and see what happens. That is the problem with daddy coaches...it too often becomes arbitrary nonsense based on politics and uninformed preferences which turn out to be wrong.
