using higher paced tactics only works if your stamina is low enough.
You chould take care to choose a good scrimage.
if you play a team way better then yours, you'll have your starters play most minutes, while the back-ups won't play much.
If your team is way better, the back-ups will play the entire 4th Q, mostly causing them to get almost as much minutes as the starters.
If the other team is almost as strong, you'll most likely have a nicer spread of 30 to 35 for starters, and the rest for back-ups.
Also difference in skill of your starter and back-up can mess things up.
if the back-up is much weaker, he'll only play when your team is well ahead...
There are so many details why players play many, or not many minutes, fouls being another factor, that it is so dificult to regulate them all...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
