Yeah, I think that Warrior team is a good team, but maybe 50 win team, at best, without Curry, not even close to legit contending. The way he is playing right now, he could be putting up those numbers virtually anywhere. No one is leaving him open, he is drilling these shots with guys defending him to the best of their ability... he just embarrasses them.
Its incredible what he is doing, its hard to quantify it compared to some of LeBron's seasons because LeBron carried a very different load for his team, especially in Cleveland, but its certainly the best offensive talent I've seen in decades. The only comparable offensive impact I can think of from a single player would be Nash during the 04/05 and 05/06 seasons when he won us like 25 games more than we would have without him.
I think his best comparison is Nash, only Nash without the back problems, more athleticism and no-conscious. Maybe some kind of perfect blend of Nash and Ray Allen.
