HYPOTHETICAL: The Spurs are scheduled to play in Charlotte, but the Spurs do not show up ready to play. At the end of the first quarter, Spurs trail by 10. In the second quarter, Ginobili takes over the game, including going 4/4 from 3 point range in the final minutes of the half. At halftime, the score is tied 45-45; Manu has 20 points in 16 minutes. In the second half, the Spurs come out re-energized, but they still do not match the Bobcats, who continue to play over their heads. In the final seconds, Manu misses a three-pointer for the win. Final Score = Charlotte 90, San Antonio 88. Manu's final line is 40/5/2 in 35 minutes with 72% shooting, incl. 88% from 3 pt. range.
In this example, was Manu "clutch" or not? Obviously, if he does not have a near career game that night, the Spurs are never in a position to win in the final seconds. On the other hand, he missed a wide-open three-pointer that would have won the game. In my opinion, the critical period in that game was not the final seconds of the fourth quarter, but the opening minute or two of the third quarter. Manu puts the team in a position to win, they pretend to listen to Pop at halftime, then the rest of the team proceeds to lay an egg in the second half.
My point is that when something like this happens, there is always a certain percentage of people who attack the player who misses that last shot. Sometimes this may be justified, but I think most people would agree that the above hypothetical tends to show just how reliable Ginobili can be under extreme pressure. In the example, the rest of the team's play put Ginobili in a situation where he had to be perfect for the team to win. Missing that last shot says nothing about how "clutch" Ginobili may or may not be.
Okay, an extreme example, I know. However, it was just this sort of thing that got me started down this path. Fans assume that we can appreciate and interpret just how "clutch" a particular player is based on their play. I am saying that you still have to look at the big picture. Since the scoreboard doesn't care when the points were scored, the "true" critical moment of a particular game may not be in the final seconds.
