There's nothing cute about 50-50. Stolen bases and homeruns drive value. That's a ton of both. He's gonna finish with a 9+ WAR this year at the plate. No pitching, no defense.
If he is pitching and keeps up this level of offense (which won't be easy) he could legit put up a WAR in the teens. If he does, he probably moves up my list here. I've been going back and forth with him and Mahomes.
The real issue here is that while stolen bases and home runs both drive value, they do so at
wildly different rates.
Home runs are worth a lot - an average of 1.4 runs, with a guaranteed minimum of one run. Stolen bases are worth about 0.2 runs apiece - the advantage of moving a runner from first to second or even third just isn't that much, compared to putting a runner on in the first place.
The combination of power and speed to reach high round numbers in both is very impressive because it speaks to a diverse and talented skill set, but it's not necessarily all that
valuable.
Vladimir Guerrero had 34 HR and 37 SB in 2001, but his basestealing was so inefficient that he probably was just as valuable on the basepaths as Sammy Sosa, who stole zero bases. This is because Sosa was caught stealing twice, made two outs on base, and took 17 extra bases, while Guerrero was caught stealing 16 times and made 15 outs on base, with 24 extra bases taken. Guerrero moved a runner forward 61 times at the cost of 31 outs; Sosa moved a runner forward 17 times at the cost of 4 outs.
The 50-50, 40-40, or 30-30 feats are impressive, but the stolen base component is just ludicrously less valuable than the home run component, even if you're extremely efficient at stealing (which Ohtani is). It's more hyped than it is worth in terms of actual runs, and so, yes, it's a little "cute."
