It's really not complicated. You said - "I think we'd have a better chance of beating the Cubs. The Giants playoff track record is legit."
I said the Cubs are absolutely better, implying that I'd rather face the Giants.
We're talking about maybe having a 55% chance to win vs. maybe a 50% chance. Some very small, nearly insignificant difference.
You explicitly cited the Giants track record in the playoffs as a reason you don't want to face them. That's irrelevant! Pure cognitive bias.
And for the record, the "statistical data" that you would need to support your position is that past playoff success = future playoff success. You didn't do that.
I am right and you are dumb I know it's hard to admit.
