I also think that adjusting game shape doesn't get to the real issue, which is the substitution logic.
The GE seems to make substitutions when the guy on the floor has become tired to the point that the next guy is an overall better option. As a result, a player with high stamina doesn't sub out because his value doesn't drop enough so that the backup is a better option.
By that logic, most NBA stars would never be subbed out. Really they are subbed out when they need a rest in order to allow them to play at a higher level throughout the remainder of the game. Better to take a few minutes of a lesser player in each of the first three quarters so that the star is still at a very high level at the end of the game.
Yep. Which is why I pretty much hate training stamina, since I like my team to get more balanced minutes. I know last season a couple of times (mostly PL I think, though), when I'd run a slow offense and not get a blowout, Schultz would end up playing 46 or more minutes, and that's with only respectable stamina. Philosophically, I'd love to have good stamina on my players, since every little bit of advantage helps, but still maintain the ability to get at least 12 minutes if not more from my backups. I've suggested several times that there should be some sort of sub priority by position in the lineup - "run them ragged" (keep starters in as much as possible) / "rotate frequently" (aim for 24/24) / "normal rotation" (36/12ish) / "let coach decide" for example. I'd love to be able to have my three big men play in rotation at the four and five, and have the ability to have the guards/SF positions be set up so that I could put specific players in where I want them and make sure I'm not stuck running someone 44 minutes.
Unfortunately, I don't think that's happening any time soon. I'm going to have to decide whether to say "screw it" and finally train stamina now since there's little point in adding more FT training, or do some really ineffective training for Busch/Klein/Cheek to avoid having team training contribute to skill drops for my 33 year olds.
