Given that the only change is the Auto-win for scoring a TD, any result for the offense that isn't a TD does not matter in the analysis. Because those games would play out identically under the new and old rule. Of the 10 wins for winning the coin toss, 7 of them were because a Touchdown was scored drive one.
There is no reason to focus on non-TD drive in the analysis ... they do not matter.
Secondly, he "simmed" based on what? What data did he use? Just saying "I simmed it" does not matter. He gives no guidelines or statistics he used. Did he just make two average teams, if so, what averages did he used? Or did he chose two specific teams? I have GIVEN where I got my sources from. I do not trust statements without their supporting data.
Thirdly, he is focused on all outcomes, which according to his sim the old Sudden Death only had a 57% favor to winning the coin toss. And the old rule 53% favor ... but the REAL WORLD data used has the coin toss winner winning well more than that. According to his sim, the coin toss winner in post season should have been 7 TOTAL, but it was 10 with 7 winning outright.
So, if this plays out similarly in the real world, will still have the coin toss winner winning more times that not.
