I feel ya bro , it is hard to stop that pick n pop, if you have good defenders it's easier but you cant stop it everytime. Know the two running the plays and guess before they engage . If you see your small has the driver covered then switch to big and await the intercept or pop contest. If it looks like the driver has the first step quickly call for a double before he gets to the rim and have help and no rotation applied. its a about quick decisions and sometimes guessing right but I have diamond Kobe and he got clamps ya'll.
