In my opinion unless the patch fixes some of the defensive issues you have to set the defensive settings yourself.
Play off ball D sometimes. Like when you see a screen being made away from the player your defending, try not to switch instantly as the ball is being passed around a lot (unless its a paint pass) because it takes a second or two to gain full control of your defender. Run down with the center after advert offensive play. In the paint try not to hold the left trigger when defending a shot, just go straight up (back & triangle I believe).
Try these settings if you want, I use them & get good results. Just ran the Raptors off the court with my Heat.
On ball: gap on big man that can't shoot & players like Tony Allen, moderate on shooters you don't fear much, tight on good shooters, & deny on curry, klay, Durant, etc.
Off ball: auto on all bigs, & the rest the same as on ball
Go over screens & catch hedge
Ice on center screens & catch hedge
Switch on all off ball screens, 3/4 bottom post defense
Help all defense and no rotation & help all
I don't have the game in front of me right now so I could have missed a few things but I'm telling you I've had some very good defensive games with these settings.
