Sticking a kid in a mailroom isn't really on the same par with making a pro sports roster.
But see, you have an issue with nepotism when it's a guy in corporate America but not here. Regarding the guy you're speaking of, yeah, his dad obviously gave him a leg up on normal people. But just like when Vince McMahon bought WWF from his dad, they both took their business to greater heights and I don't think one could argue either case.
Sports is supposed to be the ultimate meritocracy though. You can skate through youth sports with nepotism daddy ball BS, maybe even get walk on spot in college cause of your daddy, but you rarely see that in pro sports. Why? Because your physical skills and physical measurements matter in competition at the highest level. A 6-foot-1 (yeah that's more correct to his height) shooting guard with heart problems shooting under 30% from three, and averaging 4 ppg in college, getting drafted and getting this much coverage is crazy. It wouldn't be as annoying if LeBron hadn't been pushing this for over a year and making claims like "He could help the Lakers right now."
Bronny was already born on third base and didn't need another bone thrown his way. The scorn isn't so much toward him as it is his dad. But to claim that he "earned it" is like Brad Calipari's "Earned not given" tattoo. C'mon, man. I say just own it that yeah it's nepotism instead of trying to gaslight everyone into being like "Oh, he definitely didn't get drafted here cause of his dad" like JJ is claiming.
