Well, I never imagined a lineup with both KK and Vivi on the floor at the same time. I think it is essential that they switch off in order to spell each other and to create a little mixup for the other team.
I feel like putting Treece in as the starting 4 then rotating EJ (as she gets more experience), and Maddie there. When we need some speed we can put in T'ona, rotate Maddie down. When we need height and strength, use Treece because with her in we still have that outside threat from both her and Maddie.
We really have a lot of options. I think using all our lineups throughout the game could be a nice changeup because teams would have to constantly adjust. We don't have to stick with 5 or 6 players all in one single role.
Also, the quarter system messes up the timeouts, both for called timeouts and tv timeouts. Makes the stretches between breaks longer and/or less frequent. (posted after the other replies posted)
