Wildly inaccurate post.
If we want to discuss the top statistical players in baseball history we can do that too, but that pretty much means that we can only discuss retired players who have their full body of stats accumulated.
But if we want to include talking about active players we have to be ok with not worrying about their current counting stats.
Ohtani will likely finish with north of 400 homers and 500 is attainable with good health. He's got a good shot at 100 wins considering he plays for the Dodgers and could rack up 15 a year fairly easily if he pitches well.
If he wanted to, he could get to 400 steals. The 400/400 club consists of only Barry Bonds.
He went 50/50 last year because stealing bases became a fun hobby for him suddenly and he just decided to make it happen.
If he wanted to he could focus only on pitching and win a Cy Young award. You dismiss him finishing 4th one year, but I don't recall any other MVP level hitters EVER finishing 4th before. Also a 6.1 WAR season on the mound is insanely good and is good enough to win the CY some years.
If he wanted to, he could probably forsake some average and try to hit 70 homers in a year.
The thing with Ohtani is that he can do everything you want a ball player to do, and he is elite at it all.
Pujols wasn't stealing you a base or legging out 9 triples per year
Bonds wasn't going to throw a guy out from deep left
Cabrera could barely play 1st base competently let alone a value adding position.
Maddux wasn't going to bat lead off and go 3 for 3 with 3 bombs while pitching 6 shut out innings.
There's just no real comparison to him for how you place him among the all time great, and that makes it hard not to think of him as possibly the best ever.
Just think about this, his best pitching WAR year is a 6.1 and his best batting WAR is a 9.2, that means if he could put that all together in one season he could produce a 15 plus WAR year.
https://www.baseball-reference.com/leaders/WAR_bat_season.shtmlLook at that list, 14.1 by the Babe is the current best ever and I think Shohei will eventually have a year where he eclipses that and that's despite WAR penalizing him for being a DH.
