I remember when the Reds traded for Griffey Jr., and it was literally one of the best days of my life up to that point. As a soon to be 15 year old falling in love with the game, and with the team's success coming off of the 1999 season, I was riding high with my favorite team trading for the best superstar of my generation. And even better, we didn't give up anything to get him!
Or did we? Griffey had some good years with us, and it wasn't his fault the team stunk, or that he was consistently hurt. But I think many people forget just how good Mike Cameron ended up being as a centerfielder. The history books will remind us, and rightfully so, that Griffey was one of the best of all time, and Cameron will never be remembered as such.
But from 2000-2008, the years that Griffey was a Red, Griffey had a cumulative 9.8 WAR, compared to Cameron's 31.8 (using Fangraphs). Now, this comparision isn't to pick on Griffey, but when I went back and looked at the numbers, I was absolutely stunned to see such a large differential. Who would've ever thought that over the course of Griffey's time in Cincy, Mike Cameron would end up being the better player?
