I can't understand why,
When a team is subject to a lengthy salary floor protection period, it can lead to a situation where they're forced to allocate a significant portion of their resources towards player salaries, even if it's not sustainable for their current financial situation.
Or do you mean you're not referring to regular teams here, but rather those teams that bought a lot of high-salary players before the playoffs?
I agree that a 28-week salary floor protection period encourages teams to keep their player salaries low and then buy a lot of high-salary players right before the playoffs.
But I guess (though I might be wrong) that most new managers usually don’t use this kind of high-risk strategy.
This kind of strategy is more common among returning experienced managers or new managers who were taught to do it this way.
So we might need to be careful not to teach new managers with this kind of experienced-player mindset, or it might ruin their gaming experience.
