Since the 50s, the bumping, forearm shoves, hip checking have been happening in the paint every possession.
Slashers who attack the lane draw contact nearly 100% of the time. Fouls are called on about 20% of such moves.
That's true even now with more restrictions on hand-checking & hooking & the wider court (defensuve coverage-wuse) due to the three point dominance.
Basketball was never intended to be a non-contact sport. It was designed as a no collision sport.
