Depending on the minute rules, it could even be that a team play all three players in one thrown game and then play full competitive lineups in their other two.
Uhm could it be that you "seem to be advocating" that training 3 players out of position would be "making the effort" because it requires managers to throw more games than 1? What kind of game pushes a player to lose more in order to succeed/have fun?
I'm ignoring the rest of the quote because it was just more building upon the same faulty initial premise, that you have to throw games to train players out of position in competitive leagues (and further that the game requires that). That's the equivalent of sitting in a room where the door is open, the window is shut, and claiming to be trapped in the room because you can't open the window. It's simply faulty logic - you are not required to throw games or be uncompetitive to train players out of position, unless you're at a very high level. Obviously, in the NBBA you're going to have a tough go of it, and probably in my current league I would have a hard time, but I had three eighteen year old big men that I played pretty much exclusively out of position for training from season 19 through season 21 and still sporadically after that. I was in a competitive III series, and I didn't throw games - I'd have weeks where I did the two position stuff to try to have stronger lineups when needed, and one position some weeks when I was facing an easier team, but I didn't throw games.
So I categorically reject the premise that it "can't" be done and that the game "pushes a player to lose more in order to succeed/have fun?" I mean, I ended up fifth all three seasons, though I'm still bitter about a buzzer beater dunk at the end of the last game that meant I missed the playoffs by two points of PD. It was not as easy as just fielding a cookie cutter lineup, of course, and it required me to think about what I was doing, but those appear to be things about the game that others might like. I know I enjoyed the competition and the challenge.
