I usually wait for the ball to bounce back up into their hands before I reach for it. It's also better to use the body up animation while reaching too you can better animations

Also Gold/HoF pick pocket is OP as hell once you figure out timing. I get 5 or 6 a game

Try sprinting away with the right stick and R2, away from the ball handler

Maybe stop reaching

It’s a 50/50 chance and sometimes it looks easy to get

Try initiating contact before you reach bro and time your steals.
