If you look at players in top 10 convos only two...Bird and Bron...came from the trenches. Not sure where this trench talk with the NBA came from. There is a reason AI stood out like he did. He aint do nothing but be a hood nikka and became a superstar antihero as a result.
I’d argue media training and brand consciousness at a young age has more to do with players not coming across as “authentic” as previous eras than not coming from the trenches
Though there is validity to the barriers of entry today being harsher than they were then
