During Playoff you can't set your enthusiasm to TIE (take it easy).
So you can play with normal ent. or you can play CRUNCH TIME.
Either one you choose- your players will try that much, but ent. won't act same as during the season.
If you play NORMAL, your enthisiasm will raise as if you set TIE (it will raise for 1/3);
and if you play CT, your ent will stay as if you played normal ( BUT it will drop if it is very high- above 5)
