I think I've found an answer (sort of):
Changes in Enthusiasm: With a decrease in the random factor, we can now use enthusiasm in a way that makes more sense than the current implementation. Right now, Take it Easy and Crunch Time affect the skills of the players; for example, the same player will behave as if his rebounding skill is higher when the team is playing Crunch Time. In the new version, his rebounding skill will remain the same, but he'll have a better chance at getting to rebounds that come down between players. You can think of the combination of these changes as our decreasing the random factor by averaging more dice, and then Crunch Time as a way of weighting the dice in your favor.
