Over at THT Sean Smith has been going through old data and putting together historic defensive stats. You can go download the spreadsheet that has all the info.
I have always felt like Griffey was a great defender but I was young and he dove in CF so maybe I had overvalued his play over the years. Looking at him now and the stats we have currently he looks horrible. I went through and grabbed what Sean had on Griffey.
When you look over the numbers you'll see that he wasn't that good when he was young. Probably still pretty rough because of lack of experience. He was a fine CF for around 5 yrs from 1995 to 2000 and then injuries caught up with him and killed his abilities to play defense.
I think this jives pretty well with how I believe he actually was. Am I way off? I'm a little surprised he wasn't a better defender when he was younger and that he was still decent around 2000.
PS. I do like how I can just copy excel stuff in and it looks good now.
