Later born players seem more likely to outperform draft year numbers, but its far from a sure thing and the "hes basically playing in his d-1 year" thought is bologna
I read a study a while ago regarding this issue and it wasn't as much player B is younger therefore more likely to score more than player A who is older, but players born within certain times of the year
from Canada because a lot of development programs have cut offs of January 1. Players born in summer and fall months tended to be better than those born in winter months. But the study didn't mention anything about what
position the players played. It's also an old article when advanced analytics were in their infancy. It read more like junk science from an undergrad student rather than an actual data scientist.
Correlation is not always causation.
