Valid point Chris, I'm sure Goiko scores a lot more with it than just about anybody. And my thinking is that the 'power cortada' is an entirely different shot. It is more just Goiko over-powering everybody than throwing the perfect textbook cortada. Is it effective? Absolutely, but I doubt any players in Spain playing off the back of the church 500 years ago ever dreamed of the 'power cortada' (hahaha).
It's like the debate in the NBA about Lebron James being the best. Is he really the best player, or just the most athletic/strong? I guess it's all in the eye of the beholder.
