From a legal perspective, it is not a clarification but a change. The stupider course of action is to try to pretend it's a clarification instead of admitting it's a change. The Big XII chose to take the stupider route here.
But if I had to argue the Big XII's position in court, I would point to the comma and say the rule is legal gibberish as written, so some clarification is required. The Commissioner is authorized to clarify the rules. That's what he did.
It's just the intent of the rule was clear even if it was poorly drafted, and the "clarification" completely changed the intent of the rule.
Oh well.
It’s pretty clear that they lifted the rule from the PAC-12 and the comma was put in as a typo. I still wish someone would try to FOIA communications between a school & the Big12 office to see if there’s an email/communication that contains the proposed rule during the rule voting process to see if the typo is actually in the rule or if it’s just a typo on the website.
The comma is irrelevant unless there is a way to read the rule WITH the comma that accounts for one member in a multi-team tie winning the tie breaker by virtue of beating the other members in the tie.
At best, I can think of two interpretations:
1. If not every tied team has played each other, go to step 2. [PRETTY CLOSE!]
2. "So step 1 we look at the head-to-head win percentage among the tied teams. But hell, if you don't do that it must mean every team has played each other so this probably won't work, go to step 2." [Nonsense]
