The fact that Nash missed that is not actually a good way to criticize him. He created the chance from scratch. Unlikely is all the miss is. If he keeps doing that all night, it's a good thing... not a bad thing. You really think the next time Nash is that close it doesn't go? He misses that 1/10 times and is the only guy on the roster who could have created that opportunity. He's also playing with an edge right now and looks hungry this period.
Your use of logic is going to confuse and anger a lot of people around here.
