The two options available will be "Playoff Normal", in which your team receives the enthusiasm effects of a regular "Take It Easy" but the effort level of a regular "Normal", and "Playoff Crunch Time", in which your team receives the enthusiasm effects of a regular "Normal" but the effort level of a regular "Crunch Time".
I would suggest that if you play PCT the enthusiasm effect should be the same as a normal CT.
The whole point of the change was precisely to NOT have that happen.
In some leagues, there is a huge difference between both conferences. So, while one team struggles to reach the final and lose all it's enthusiasm crunching all the games, the other one can take it easy and reach the final with a very high enthusiasm.The first team would then have no chance to win, excepted if it is far better than the second one. That's not fair for that team.The change in enthusiasm is to prevent that to happen.
