Well yes that's possible, we'd need extremes on both sides to be absolutely sure. Our NT big men usually shot half of the times against Ma and he's better than Haek was inside. I also wonder what would happen with a patient with a the outside scorer playing at PF or C (surely the scorer should be viewed by the GE either as the outside or as the inside main threat)
That would be interessting. And now go one step further. You switch the SG with the PF and play patient. With this you could create two possible patient-missmatches. The box+1 will go for the bigger threat, but the other player could still kill you.
About the third example: Haek was the +1 defender, I was just not sure if he will defend the SG or the PF. It was this case where I thought "trust the game manual or my one impression".
