My minute distribution has been much better since I posted my frustrations, but what I was meaning when I said that above, is that following the game I was frustrated about, my backcourt had 47 minutes. So if I started my starters again for the next game, then I had to be concerned about a similar minute total, in which my backcourt starters would have 94 minutes each, which is not a good thing.
So what I was intending to convey when I said that, was I wish I could play my starters freely, without concern that two games will burn them out, and then let the backups have the scrimmage. If the minute distribution is better, then obviously, playing the starters for 2 games, and the backups in the scrimmage works great...buf if your starters get 40 minutes a game or more, that is not good for your game shape.
