It’s mostly just margin of victory/defeat. I’ve tinkered with adding more advanced stats, but then it feels like I’m geeking out too much and the tail is wagging the dog. At the end of the day, your team just needs to score more than the other team and if you can do that consistently, especially against good competition, you should be rewarded.

One criterion I really would like to tinker with is home field advantage. Right now it’s just a +4 point modifier for everyone, but there are definitely some environments where it’s worth more and some where it’s less. I haven’t found good public data on that (I’m sure all the bookies have that down pat though) so it’ll take a fair bit of statistical analysis to ascertain what those values are. Maybe next off-season.
