Not necessarily if one or two of the seven guys who you think constitute your "best talent" is (or are) having an off night, or even just a so-so night. (Depends, I guess, on what you mean by "as much as possible.")You would be wasting talent if you didn't have your best players on the floor as much as possible.
I could see playing nine (or even ten) guys early in a game just trying to figure out who are the best seven THAT NIGHT, and then riding those seven the rest of the game.
Might also keep more players happy, knowing they'll get their shot (and have to earn it) every night.
(I know nobody does that, and don't expect Brad to do it.)
