Yes, such as the fact that the Spurs won with teams with and without good 3 pt shooting, and yet you claim that Duncan can only win with good 3 pt shooters on his team, right?
Oh wait, I forgot, it's not about how dangerous you are behind the 3 pt line, but what % you shoot at. We all know Malik Rose is a better 3 pt shooter than Stephen Jackson that year, because he shot 40% vs. 32% for SJax. Wait, there's more, Parker, who everybody said couldn't shoot, was actually a better 3 pt shooter than SJax too, he shot 33.7%. Damn! Finally, Malik was better than Kerr, if only ever so slightly! 40% vs. 39.5%. Malik, simply the 2nd best 3 pt shooter on the Spurs in 2003 despite making only 2 of them.
