There are some really clutch players out there. Nash and Ginobili are probably the best all around IMO, when you factor in efficiency and quadruple threat (3-point shooting too).

Here is one other thing to consider though. The Pistons haven't had that much crunch time this year because we have a pretty high average point spread. So, I guess you could say that the sample size is on the small side. Also, the crunch time games we have had tend to be against pretty good defensive teams.
