Guys like Deandre Jordan, Rudy Gobert, Tyson Chandler are a nightmare to defend. You have to change your personnel. It changes the way you guard the PNR because you either can't hedge or you have to have a 3rd player rotate that is capable of defending the rim against a freak 7 footer with momentum.
That's why those guys have crazy high fg%. Most of the time teams change up their defense to protect the rim and it gives guys like Dirk, Griffin, etc room to operate. Teams would rather dirk shoot a long jumper than let a 7 footer have an easy dunk.
