From Thomas Boswell, Washington Post:
Amid the welter of modern stat tools, one idea often gets buried: The difference between a great or near-great player and an average or slightly above-average player is enormous in terms of glamour, fan appeal, all-star and even Hall of Fame consideration. But the difference — on the field, in run differential and in the standings — often just isn’t that big.
For instance, Bryce Harper is on a Reggie Jackson-like Cooperstown track. He is worth a lot more than the frequently mentioned “replacement player” who is a bench warmer or Class AAA call-up. But how much more is he worth than an average MLB player? That’s a different stat, called wins above average. In 2019, Harper was worth about 2.2 wins more than an average right fielder. For all nine years of his career, he’s worth about 2.1 wins per year more than an average player.
The Rays, A’s, Marlins, Indians, Twins, Royals and many others will never be able to afford a Harper in free agency. How can you get around it?
In 2019, the entire Rays team was 11.7 wins above average. That means that they should have won 11.7 more games than an 81-81 team — or about 93 wins. The Rays played well in one-run games and won 96.
How did they get those 11.7 extra wins above average? The Rays had 10 players whom they paid about $7 million in total. A few were good, cheap prospects. Those 10 produced 10.2 wins above average.
Who were these stalwarts? Willy Adames, Ji-Man Choi, Yandy Díaz, Austin Meadows, Tyler Glasnow, Nick Anderson, Yonny Chirinos, Oliver Drake, Emilio Pagán and Ryne Stanek. No, I don’t know many of them, either. The Rays also had several other (0.0) average guys. They helped because avoiding negative players boosts you, too.
It’s tough to win a World Series with 15 or more “average” players on your low-budget roster. But, this October, if the Rays, A’s or Marlins somehow advance, you might want to pull for them. In a way, they are the teams that are truly remarkable.
