How do I pull a Draymond on these guys

Is there a reliable way to block dunks from the enemy team? Or do I just have to get lucky that my players do it automatically or I jump at the exact right time needed?

If not, let my players pull a Draymond Green and drag them down or something. I wish there was a way we could injure the players then so I stopped getting dunked on this is starting to get embarrassing
