No it isn't - you simply misjudge it because you don't understand it. That ain't positionless basketball's fault.
And who said it isn't? You miss the point. Positionless ball says that not only do you need those skills, it's great to have more than one player excel at them - and more importantly, that those skills mustn't exclusively stem from the PG position.
Just watch Wemby roll on, and you'll catch on to it pretty quickly at the pace he's going.
