I didn't watch one second of that game, but there is no universe where Austin Reaves -- who is neither a physical post player or someone relelentlessly attacking the basket off the dribble -- should be getting to the free throw line that many times.
Really, it's okay for the offensive and defensive player to make contact and not call a foul. It's called a "no call" and the league had it forever and everybody was cool with it. Hell, they used to do it on block/charges all the time and people were still okay with it. Plyaers would collide, the ball would roll out of bounds, they would usually give the ball back to the offensive team, and the game would go on. And players would stay on the court because they weren't getting in foul trouble with bullshit ticky tack calls. Somehow, we all managed to live through it and actually enjoy the games instead of this idiotic ass parade to the free throw line.
