At our HS, many of the parents (who are coaches) in the stands could easily take the group that shows up to our HS tryout and win just as many games as the HS head coach. His ACs are quite good, and many players see them for hitting and pitching lessons year-round, but the HC doesn't do much more than make the lineup and look grumpy. His players show up ready to go, and he gets to choose his "all star" group from the travel teams that ultimately trained them.
While I wish I had a few more experienced players, I'm not sure I would like to be in that situation either. I like actually coaching. When I want to make out a lineup and simulate the game, I play OOTP.
