You can pretend Ichiro never even played in Japan and he's still a first ballot Hall of Famer. I think he'll play into his 40s and surpass 3,000 hits, career batting average well over .300, Rookie of the Year and MVP in the same season (absolutely ridiculous), 10-straight 200-hit seasons (ridiculous), 10-straight Gold Gloves (again.... ridiculous), 3 Silver Slugger awards (very impressive considering he isn't a power hitter), he'll probably also surpass 500 steals (one of 37 players ever), two batting titles, and although he's only had 19 career postseason games -- he's a career .346 hitter in the playoffs with 4 steals, 4 doubles, 8 RBIs and a homer.
I think it's safe to say that if he played his entire career over here, not only would he have an outside shot to pass Pete Rose for the all-time hits leader, we very well could have him in the conversation as one of the greatest players to ever live. I don't think his .300+ average would be out of the question, to go along with 15+ Gold Gloves, 1000+ steals, and a cache of other accolades. Ichrio will always be one of my favorite players. What a classy guy. It'll be a sad day when he retires.
