I'm trying to give Earl Scroggs more minutes per game, as I expect him not to get many minutes in a team running a Fullcourt Press, has 10 players that will get minutes, and only average of 72 stamina(the players getting minutes) with my starting SF Thomas White having 93 stamina.

He only got 9 minutes, in a slow paced tempo, which I plan to run in most of my games.

I'm thinking I should have him backup, or start at PF.  My current starter at PF is Ovral Mansell.  Even though Mansell is a better rebounder and blocker than Scroggs, his IQs are D-/D- while Scroggs is B+/B+.

What should I do?

Maybe start White at PF and Scroggs at SF, with the low IQ Mansell should not be starting.  White is a better rebounder and a worse passer, Scroggs is a better defender though with the high ATH so consider swapping the two if the opposing team has a really good offensive PF and a bad offensive SF.

That sounds good, thank you for the idea.
