Box-and-One defenses: Four players play in a zone defense protecting the basket while the fifth player plays a man-to-man defense guarding the best offensive player on the other team. This prevents him from scoring as much. There are two types of box-and-one defenses:
Inside Box-and-One: The fifth defender focuses on the opponent's best inside scorer. Normal pace.
Outside Box-and-One: The fifth defender focuses on the opponent's best outside scorer. Normal pace.
Could it be, that the "fifth defender" in Inside Box-and-One is the C and the "fifth defender" in Outside Box-and-One is the PG?
It could also (not likely!) mean that the PG (the others positions are selected to the four man inside box) defends the best scorer, both in Inside Box-and-One and Outside Box-and-One, since the PG(or rather the position) is the fifth defender(position wise) when calculating the zone?
It's not a crystal clear explanation in the manual!
I sincerely thought the Outside Box-and-One one was a four-player outside zone and the C, i was thinking "Outside box" + "and one" to begin with. :-) No wonder it didn't work the way I thought it would! ;-)
But when I read the rules again (and again) I assume, that in ANY of the Box-and-One defenses you need both OD and ID (and SB and RB[more in Outside Box-and-One] as well) since the four man zone will defend against both outside AND inside players and grab rebounds!
