Thanks for the quick reply. I know there is no guarantee for the minutes. Though I think it´s not really perfect that a backup player gets 1 1/2 minutes of action in the first quarter, then sits on the bench until 1:26 left in the third quarter. While the starter has awful stamina...
I would expect these substitution patterns more from the reserve player.
If you don´t wanna call it a bug, maybe it´s still something worth looking at?
