In my work, I’m not building rosters, I’m trying to figure out who the greatest players of all time were. For this reason, WAA might be a better metric for me to use than WAR. When considering someone for the Hall of Fame, do you say “Wow, he was so much better than the AAA players of his day?” or “Wow, he was so much better than everyone else?” I find WAA is a better way to measure how much a player was better than “everyone else”.
Why? WAR rewards you for just being there. WAA does not.
62% of WAR is Just Showing Up
For Pete Rose, it was.
Pete Rose was worth 76.7 WAR for his career. But he was also worth just 29.2 WAA. That’s a huge difference. Take Charlie Keller. He’s on the opposite end of the spectrum. Keller was worth 40.6 WAR, but 29.0 WAA. Yes, King Kong Keller’s WAA was about the same as Pete Rose’s.
What’s happening here? Rose played forever (15,890 PA). Keller didn’t (4,604 PA). WAR rewards you for playing time, as long as you’re better than a AAA player. WAA, meanwhile, will rip you apart if you’re below average.
