So I've had this conversation with a number of my friends, and seeing as how baseball excitement is nearing its peak (culminating with the oh so heavenly Opening Day), I thought this would be a time to ask this question to the very knowledgable baseball crowd that posts on this site.

DISCLAIMER:  THIS IS NOT A MINOR LEAGUE QUESTION

Who is the greatest player you have ever seen?

I'm 22 years old so I haven't seen many of the great players of the 70s and 80s, yet alone the Golden Era of baseball.  For me, the best is Ken Griffey Jr.  Not only was he the cleanest of the "Steroid era," during the 90s, he was the complete player (10 all star games, 10 gold gloves, and 7 silver sluggers).   I've seen video of Mays and Aaron and others, but I've seen Griffey play (both on TV and in person).

So, who's the best player you've ever seen?  Pitchers or hitters or both
