Thanks everyone!
One striking thing about this tournament was that I ended up thinking that for almost all the leagues, deadball pitchers were not the way to go. I used one or two when they made sense, but mostly I thought they didn't.
Now obviously winning comes down to lots of luck, and I wouldn't say that winning proves this was right. But until recently I wouldn't have thought anyone had a chance if they didn't use deadball pitchers. Now, clearly, they do.
Part of what changed was the messed up way dynamic pricing was introduced. And partially this is because the mid-2010s pitchers are much much better than other live ball pitchers, especially other starters.
But largely it's because everyone has so internalised the idea that everyone uses deadball pitchers that they are using doubles and triples hitters rather than home run hitters. And Sale/Kershaw/Arrieta/Scherzer etc are much better against those hitters than any of the dead ballers who didn't get priced out of contention by dynamic pricing.
So hopefully we'll see many more modern pitchers in the game soon. And then people will start using more HR hitters, and it will all get a bit more interesting, and a lot more like familiar baseball.
