Actually, it's no PG and 5xSG. Either way, I don't care. The "best position" as shown for the player isn't necessarily their best position, as far as I'm concerned.
Best Position: As with the DMI, this is a very rough guideline, and some would even say a meaningless one. You should play your players at the positions that make the most sense to the team, regardless of whether it is his listed position.
