In my Private League games I've been experimenting with Let Coach Decide.
In this game I submitted a blank lineup card (no starters/backups/reserves assigned) with Let Coach Decide:
(17527977). Minutes were spread out pretty evenly and everything made sense.
By contrast, in this game I set a starting lineup but no backups/reserves with Let Coach Decide:
(17527980). The starters played all game except for some chess-match substitutions at the end to shoot desperation 3s or rebound FTs. That's not very much decision-making by the coach
My bench is fairly talented (relative to my starters) and Havens in particular is not a usual starter, I find it hard to believe there was no need to sub all game.
If the starting lineup I set in game #2 was disregarded and didn't take the court at all I would chalk it up to coach's decision and that would make sense. If substitutions occurred sort of "as appropriately", that would be coach's decision and make sense. Having the starting lineup I set go out and play all 48 minutes is what "Strictly Follow Depth Chart" is for, so I feel like the behavior I witnessed needs to either be documented or fixed.
Yes, I'm sure I had Let Coach Decide set on both games. I double-checked it in the "re-use previous tactics" drop-down.
