It's separate.
I think I wanna go for both, but I think I'll wait to see some reviews and in hand pics of the hoops before deciding. MY is a no brainer for me though.
That hoop is just massive, like 24 inches high and probably just as deep, plus probably close to 12 inches wide, just too much space to lose. what would be a nice option is a backboard and rim you could just mount to a wall or something.
