I'm going to love arguing with Ape on this one...LOL!
In my opinion, and most baseball writers out there, Griffey is not the MJ of baseball. After all, would anyone here say that there were 55 basketball players better than MJ? Probably not. But according to modern baseball statistics, there were 55 baseball players who single handedly helped their teams win more games than Griffey. And the ability of one player to contribute to wins is what really measures the worth of any player in any sport. That's over their respective careers. Now, some might argue that many of those players enjoyed long careers, but then again, Griffey played well past his prime as well, milking his days with the Reds long after he was an average hitting outfielder. We can all speculate what might have been, had he not gotten hurt. Maybe he would have hit 700 homeruns. We can say the same about Pujols and his fascitis.
So let's try to take Ken's best season - 1996 - and compare it to Trout's best year. In that year, Ken had a 9.6 WAR value. Trout was 10.9.
Ken only had two years where his WAR stacked up over 9. Trout's done it his first two years. His first two years in the league have been better than any two Griffey years combined. So that's saying something about Trout, and about how decidedly "un-MJ" Griffey really was.
Some guys don't see the merit in WAR though. Understandable. What about adjusted OPS? Take Griffey's two best years, and they still don't match what Trout has done in his first two years.
Why the love for Trout? Far from it. I think Trout is great, but he's not the greatest. I'm simply using him as a yardstick with which to compare Griffey. We wouldn't run around saying Trout's years are the greatest ever. Nor should we say the same about Griffey. Now, Griffey did produce at a high level for a long time, and because of that, were I voting, he'd be a first ballot HOF'er on my list - no questions asked. But then, I would have also voted for Palmeiro and Bonds.
Griffey was great. But he was far from being the greatest ever, or even the greatest of his generation.
Oh, and if Griffey was so fast, how did he get caught stealing over 70 times on 180+ steals? Trout's been caught only just over 10% of the time. Maybe Griffey liked getting caught? Maybe the catchers in Griffeys day had better arms? Or maybe he's never been as fast as Trout.
