Here’s a challenge since you think Otto Porter proves a point:
How many American born NBA players do you think there are who opted not to play competitive summer basketball during their high school career in the last ten years?
I’ll bet, judging by your post, you have no idea.
And, I’m quite certain you have no idea how many of the nearly 3,000 American born scholarship players who were signed as high school seniors on D1 rosters did not play competitive summer basketball during their high school career.
Just because Neil Armstrong was a person and walked on the moon does not mean all persons are astronauts. The Otto Porter example as something that proves a larger point is uniformed claptrap.
