It seems this guy is really overrating the prevalence of this now and going forward,
I mean he says "Finding an alternative to college is on the fast track from anomaly to normalcy. Hampton’s decision is emblematic of the attitudes of high school basketball players toward college as we hurtle toward potentially seismic changes coming to the NBA draft in 2022." and then uses 4 examples and the always technical "and a few others."
And it isn't like the guys mentioned are super star recruits or stud NBA players. Sure Mudiay was ranked high but had a lot of questions about him that seem to have become true in the NBA and with his decision to go to overseas.
Sure college is not for everyone, but it isn't like these guys are forced to take Senior level astrophysics and really most of these kids should realize that taking advantage of a college degree, a chance that many of them wouldn't have had without basketball, is likely the best way they have of maximizing their future earnings. Top recruits every single year fail to make it to the NBA let alone guys ranked lower.
If someone is against going to school then they shouldn't go but acting like going overseas is a better option than going to college is pretty silly to me.
