If we harken back to last year's discussion about luck i made a very complicated and potentially useless measure of luck that took some of these things into account;
1. Being the #1 for the week was somewhat lucky.
2. Being the #14 for the week was somewhat unlucky.
3. Facing the #1 for the week was very unlucky
4. Facing the #14 for the week was very lucky.
In the first two cases, your luck is somewhat determined by draft and roster choices.
In the latter two cases, your luck is mostly determined by who you faced and their roster and draft choices.
Imagine the most extreme scenario where your team goes 0-13 because you played the #1 team each week. And each week you came in 2nd place overall. Also, imagine the opposite where you go 13-0 where you played the the worst team each week and each week you're 2nd to worst.
If we were running a league where that happened, it'd be hard to imagine anyone thinking the 13-0 truly deserved or earned their spot at the end of the season.
Maybe the best tie breaker measure is to count wins vs. league as a tie breaker.
