I think the guards try to find the inside isolated player but if the inside defense is too good they have to shoot the ball themselves.
box and one, regardless of outside or inside, will always have 4 guys kinda playing zone and they will collapse on the inside guy when they get the ball so they will have to kick the ball back out to the guards who will then have a brief time where they can shoot the ball or pass it around.
people have the offences around the wrong way.inside iso is more what the magic do - its a strong outside offense thats started by a strong inside player.outside iso is basically the opposite - a strong outside player will drive to create his own shot or to create a pass to an open player.both are balanced - but inside iso will get you more threes and in most cases will have your guards scoring more.
