It's because of the influx of players who spent limited or no time playing in college. So you end up with a lot of raw talent that needs a LOT of refinement in most cases.
I agree. I think the way players come up has a lot to do with it too. Back in the day nikkas got refined in college but they came in with basic elements of a post game. Now nikkas are just raw as fukk getting by on being bigger, stronger, and faster than everybody.
