Easy way to know if its true or not.
Can you give me an example of amothe basketball player who started playing bball at 16, was not allowed to play college ball, was drafted by a team with a rookie coach, had a major injury at the end his second season and was unable to train properly in the offseason between his 2nd and 3rd year, then had his role and minute change a bunch over the course of his 3rd year, and was playing for a tanking team with a lame duck coach on his way out?
If you cant, then there is a good chance that it is unprecedented.
