I don't dispute your valid points, nate -- not at all. But, they deserve comment. So...

Absolutely correct. Neither box score data nor any other kind of data can "capture everything."
But, tell me, have you looked at Giannis's box score data? How about LeBron's box score data? How about, historically, Michael Jordan's box score data.
Should we also ignore their box score data, because "box score data doesn't capture everything..."? Does box score data capture nothing at all, or even just say nothing
important, about those players?
To put it slightly differently, don't you think you might be downplaying box score data in the case of this comparison precisely because you have a settled opinion about the players in question? Just something to think about -- not to reject out of hand, nor to accept automatically either, but to think about.

I don't give "the smell test" a whole lot of credence. & I don't give individual on/off numbers much credence either. Wasn't it you who pointed out that... I don't remember who... came off the bench & played against bench players? Isn't that true of Bertans? Should we ignore the fact in this instance, while we accept its relevance in the other?
Or, instead, let me reproduce your statement with a slight difference of players: "Bradley Beal has an on/off differential of -4.9 per 100 possessions. Bertans has an on/off differential of +8.1 per 100 possessions. Arguing that Beal has been better than Bertans doesn't pass the smell test."
Any problem with that analysis? Admittedly, -4.9 is a little better than -5.8. Bertans is plus 13.8 vs. Bryant & only +12.9 vs Beal.
Of course, you wouldn't suggest that the comparison has any significance whatever when it's Bertans vs. Beal. If I used it as data to support the idea that Bertans is a better player than Beal, you would scoff at the idea. But... if the value of a comparison of data can't be judged until we know who is being compared... well, then, that data -- unlike box score data -- is altogether irrelevant.

The team has played its best basketball with Mahinmi at center, posting break-even on/off differentials against the opposition's starters.
I don't know about "exceptional," I agree 100% that his value would/will increase as he got/gets better at those skills -- & we don't know that he will get better, though we can hope he does.
At the same time, of course, every player has flaws. Bertans isn't a particularly good defender -- though a bit better than Bryant if you trust DRPM. & Bertans is a really bad rebounder. & that's a really big problem.
It ought to be easy to see that no matter how efficient a scorer you are, if your minutes mean that your team has fewer chances to score than otherwise they would, that differential impacts the meaning of your individual numbers. You have no trouble seeing the impact of one guy's play on the rest of the guys when it comes to spacing; surely this should be equally obvious. Actually, it's a lot more obvious, & its impact can be calculated with far greater precision.
I like Davis Bertans. I was aware of him before he ever played in the NBA. When San Antonio picked him at #42 in 2011, I was aware of their doing so & had the thought that once again SA had demonstrated their ability to get the value out of the draft.
IOW, I'm not a Bertans-hater. & I don't think you're a Bryant-hater either. My post was about what I said it was about -- the weird fact that "everybody" (i.e. most people) are ok w/ the idea of paying Bertans $15m a year, while at the same time suggesting Bryant in potential trade after trade. That makes no sense.
