Ichiro is a fascination in the since that he is was the top Asian player in the game and he came over and could actually play at a really high level. He helped to bring about a trend in getting more japanese, korean, chinese, etc. players into the MLB system, and at an earlier age.
Is he a great player? Eh, he's probably top 150 hitter of all time, so at least close. In the 2000's, he was probably around the 15th best, maybe? I mean guys like Beltran, Berkman, Chippa, Manny, Miggy, ARod, jeter are all probably better of the top of my head - probably a few more in there.
