It'd by design. It's way easier to reach and steal as well as block... that's because people want more engagement while playing. Nobody wants to play a game where they just sit and wait for the right chance. I have played some other 2ks since I put 17 down and trying to play them like this gets you laughably owned. I feel like somehow I have gotten worse at the game because of how bad I am at the previous versions.
I really like the idea of making it more physical so maybe it could be physical/stick engagement to have people constantly pushing, releasing pressure (like you would when playing D) and getting it right so you could make people miss and get a better block.
But since they want, it seems, to have defense be very heavy on square and heavy on triangle... they can't really add fouls or bad outcomes because the people who they want pounding the controller would be fouling it. I kind of agree that button mashing does engage people, though. But I think they could make it so that, as I said, the engagement could be subtle position and bumping opposed to just steal steal steal or jump jump jump.
