Maybe I'm just blind but I don't see the Bucks user running a zone defense or the Nets user missing multiple open shots. In fact, it was the Nets user who tried running a 2-3 zone for one possession, and the Bucks user missing a couple of open shots.
You even hear the Nets user say with ~1 minute left in the first "he knows this guy (Claxton) is the weak spot... I don't know how you score". That's what any modern defense in real life will do. Put their best help defender - Timelord, Draymond, Giannis, etc. - on the worst shooter and let them roam free. If you wanna score, take that bad offensive player out and make them cover someone real.
As for "green only" games, I'm not a huge fan either. I prefer 2K14-style shooting. But 2K has seemed to make it easier over the years to green shots, and that makes it easier to reward good ball movement and open shots because you'll always have control over if your shot goes in or not as opposed to leaving it up to RPG. If you were to play with some form of real player %, the best shooters would still only be hitting ~45% of their wide open looks which most people would probably take an issue with.
