I'd call it more inconvenient than illogical. ... playing sub par lineups ...
And the real life basketball league where that is necessary, where a guy doesn't get coached and trained at all unless he plays in the regular games, where the last two or three guys onthe end of the bench (who need training the most) don't get trained ... the real life basketball league where that happens ... is ...

Come with me, if you will, to another dimension -- a dimension not only of sight and sound, but of mind. A journey into a wondrous land where practice may indeed occur behind the scenes, but where true experience and training comes only from playing in league games, national tournaments, and scrimmages. And thus, managers must make a fateful decision every time their team takes to the arena: do we play to win, or do we also play to train, shaping our future for seasons to come? It is this battle of minds, savvy, and wits that creates the drama and intrigue of this land and league known only as... Buzzerbeater.

I get what you are saying now about it being illogical compared to real life, but if you were allowed to train anyone in any skill at any time, that would just be too easy. The current method of training makes things more interesting, and leads to tough decisions where managers have to gauge whether to train or play their best lineup. Or, if they are well developed they can do both. I may be in the minority, but I like it the way it is.
