If LeBron James decided to apply to Princeton, or Harvard for that matter, after he retires, I expect that he would be accepted with open arms.
I totally agree Lebron would be a great Harvard addition, though I am not sure he would play over Zena.
The question isn't about 1 superstar who is the 2G.O.A.T
What about Karl Anthony-Towns, Jahlil Okafor, Andrew Wiggins, Jabari Parker, Nerlens Noel, Anthony Davis, Michael-Kidd Gilchrist. Or Kyrie Irving, Enes Kanter, John Wall, Demarcus Cousins, Blake Griffin, Russell Westbrook, Kevin Love or even Carmelo Anthony.
Would all these players be accepted with "open arms" to Harvard today or would any of them have to go through the same application process as anyone else? These were all one and done players who were highly recruited to big name schools as consensus top 50 players out of high school.
