I personally do believe players can rise up to a situation more often or not. Whether you call that clutch...I don't know. Perhaps it shows up more at lower levels when nerves can get to a person, but I do think the way a persons body reacts can affect their performance. I found this quote that I thought was interesting. According to psychologist Tim Woodman, "when people are low in cognitive anxiety, or low in worry, the difference between their best performance and their worst performance is not very big. They can perform pretty well, but it's not fantastic, and it's not crap. But if you put them in a very high-worry situation, like Olympic Games, what you find is that their best performance is significantly better than before and their worst performance is significantly worse. So what that tells you is that when you're under a very high-stress situation, you either perform very well or very badly."
