I think this type of reasoning is exactly why these discussions can be toxic. Don't take Seth's opinion at face value. He has a pretty strong bias, and plus he's talking in a circumstance where he's upset and emotional.
"We started switching things a lot more after their big hit two threes." Yes. That's what you do. Imagine if we didn't switch and their big hit 5 more threes! People might not have liked that.
Too often, people don't think about the opportunity costs. There are tradeoffs. Just because a strategy didn't work doesn't mean it's stupid. It doesn't even mean it was wrong. If you offer me 10:1 odds on a fair coin, I will take that bet every time and it's clearly right of me to do so. And if I lose all my money on 5 losing bets in a row, it was still smart of me. It was just unfortunate.
That's the problem in post hoc rationalizations and analyses.
