The Wizard
I think we’ll start with the names. Who is first? Well, it seems to me the best place to start is with the best defensive player of all-time. I am one of Ozzie Smith’s biggest detractors. I suppose the only person whose defense I consider as overrated as Ozzie’s is Andruw Jones, but when the title awarded is “Greatest of All Time”, it really isn’t difficult to be called “overrated”. That’s a very high rating.
I always have thought the Wizard of Oz was a great fielder. One of the best. My position has generally been that while he is a great fielder, he is not some defensive god that is somehow unapproachable by any other defensive player. Yes, he had lots of assists and a big range factor (RF), but he also always got a lot of ground balls hit to shortstop. Garry Templeton had some great RFs in St. Louis and San Diego also.
We don’t have ZR for Ozzie’s peak. He was a stellar defensive player from 1978-1986 and thirty years old before I get to see his first defensive ratings. As MGL and Tango have noted, defensive skills decline like offensive skills do, so it is a reasonable assertion to think that whatever numbers we see for Ozzie, we can assume that his peak was slightly higher, and the seasons we have are somewhat during his decline.
For Oz, we have 10 seasons and 10,000 innings played. From 1987 to 2005, no other shortstop in baseball saved as many runs above average as did Ozzie Smith. Over his career, and based on the gap between Ozzie and nearly every other shortstop, it is more than reasonably argued that he is the greatest fielding shortstop of all time. And again, this is almost all decline phase – or past-peak nonetheless. I think he was on a plateau for a decade. In the NL, the closest shortstop over his career was still more than fifty runs behind.
For the decade, Ozzie was 130 RSpt. Going through the data, it is quite amazing that any player stands that far above his peers.
