This would be true if he was only able to handle certain things so shutting them down would be easier. He's working with a makeshift offensive line and receivers that are C and D grade. He's doing unconventional things and isn't showing tendencies. Defenses are already throwing everything at him and he's overcoming some of them with athleticism. It wasn't a throwing exhibition as much as heart, determination and unbelievable compete level.
Defenses should be doing exactly what they're doing but he's winning some of those battles. What would you suggest they do, rush him more? Shut down the run? Take away his favorite throwing lanes or outlets?
I think the more they try and take away the things he's doing - the more conventional things he'll be able to do.
