I'm a week late on this, but terrific piece on The Athletic by Keith Law and Eno Sarris describing the five tools and what they mean from both the scouting side and the analytics side.
"We really don't need the whole commercial break/warm-up routine every time a new reliever comes into the game. It certainly made sense in 1884 when they only switched pitchers when the starter was attacked by pickaxe or caught consumption, and no reliever was warming up because he was busy gambling and drinking." - JD
I still think I'm going to wake up and say "I shouldn't listen to the podcast before bed, I dreamed the Sox signed a guy from Curaçao named Charlie Zink." - KOC
