I'm trying to wrap up my contributions in this thread, and I agree with most of your reply, but I want to explore this thought a little further. As a refresher for others who may be reading, there's BA, there's OBP, and there's SLG - they are intertwined. A good portion of SLG comes from BA, so to "isolate" the extra-base power component somebody once cooked up ISO, which is SLG-BA. ISO for a guy like Judge can be above .300, while for guys like Luis Arraez it can be under .100. Right now Keaschall's career ISO is .108
I took a look at all the guys in 2025 who had an ISO .108 or below, and found that Nico Hoerner scored 89 runs, Xavier Edwards scored 75, and nobody else (not even Arraez as I occasionally mention) scored as many as 70. Meanwhile thirty-two other guys scored more runs than Hoerner - Ohtani and Judge scored 146 and 137 - but they and the other thirty all had ISO above .108
Turning to 2024, it was Hoerner again at the top with 86, and four other guys with at least 70. Thirty guys scored more runs than Hoerner that year but, again, they displayed extra-base power.
There is this narrative that there are table-setters, and then the guys who drive them in. The irony is that when looking for high run-scoring results, it's not the table-setters who show up in the rankings. Are all the RBI guys across the majors failing to do their job in driving in their table-setters? Or is the narrative itself in need of revision?
So back to your comment. A lot of guys have nice OBP. So it comes down to what you mean by "support." If the player's goal is to be "just a guy" in the majors, it happens all the time, and OBP can support that. But without the power component that ISO measures, their run-scoring potential is severely limited - if you are aiming for players who can be difference makers, I mean. Someone dismissed another post of mine by asserting that I was trying to equate Luke with Shohei and Aaron, and that's not the case - we're so used to pedestrian performance on our team that it's good remind ourselves what the high-end really is like.
But my interest in Keaschall is whether he can do something more that makes him better than "just a guy." Otherwise the incentive to invest much more in his development diminishes. He's trending at present toward Trevor Larnach territory, with uninspiring defense and a batting resume that doesn't elevate him, and at a certain point in a player's career we tire of him and clamor for something better. I'd like to see Luke get off that trend if he can.
Finally, in the bigger picture, I'm concerned that where it comes to drafting and developing, our few success stories are in the tier of Larnach and Keaschall.
