Didn't see this posted but really interesting story about the increasing practice of holding back basketball prospects in middle school to give them an advantage to become elite prospects. Some examples: Andrew Wiggins, Nerlens Noel, and Shabazz Muhammad. The four top rated prospects in New Jersey in 2014 & 2015 were all held back a year in middle school (including Karl Towns). The other interesting part is after some of these kids become elite, they skip their junior year to reclassify as seniors to get into the NBA earlier (Andrew Wiggins, Nerlens Noel, and Karl Towns).
Discussed at length on the Jalen Rose podcast:
