So the differences is that, because you TIE'd and he Normaled on the 21st, the difference in enthusiasm score for the game on the 24th would be larger.
eg: Lets say goign into the game you had an Enthusiasm score of 9, and he had a score of 6. You Tied, he Normal'd. So on the 24th, your enthusiasm score would have probably spiked up to about 12, but then drifted back down to about 10. His Enthusiasm would have gone back to 5.
So on the 21st, the enthusiasm difference was 3. On the 24th, the difference was 5. (roughly).
Ok so i think something to look at are the Game Ratings (Inside Scoring, Outside Scoring, Permimter Defense etc)
You will notice that the HCA slightly improves your opponents ratings.
However you will then notice with the Points Per 100 possessions, the differences really start to shine through. your SG gets much higher, and etc.
So what will happen is the enthusiasm difference will extenuate any advantages a player might have And likewise, reduce the effectiveness of the opposition.
In saying all this, you asked the question about randomness. yes why did your SG suddenly decide to explode for 21 poitns when in the first game he only hit 8?
Look at the Points per 100 possessions....- Game 1 - 109... game 2 - 134 AND this was the highest. So it could be tht, basically the enthusiasm difference really highlighted the matchup difference between your SG's and so your's went on a scoring rampage.
WHy did the enthusiasm benefit your SG more than your other players? This is probably where some randomness comes in, but also the fact tht the game doesn't work with linear differences. A bit like an earthquake richter scale, 7 is 10 times stonger than 6. (this is actually just my opinon, not fact). NOt saying that Proficient is 10 times stronger than Strong, just using that as an example to say that the differences are not linear.
