You sound like someone who wants to like him, and ignores the blatant stats that show he is nowhere near GOAT in MLB. The guy hits home runs & steals bases, but he doesn't hit HRs at the rate that Babe Ruth did, and he doesn't steal bases like Ricky Henderson, Lou Brock, Billy Hamilton, Ty Cobb.
His career batting average is .2815. That puts him at # 622 on the all time list - 621 guys with higher averages than him. Dozens of these guys who are higher than Ohtani on the batting average list, are names you probably never even heard of.
How about >>
George Stone - .3008
Paul Hines - .3020
Dale Mitchell - .3122
Rip Radcliff - .3110
Bake McBride - .2992
Magglio Ordonez - .3090
So these guys didn't NEED to steal bases. They got extra base hits (lots of doubles-they were already on 2nd base)
