About close games:
It is purely anecdotal that "good teams win close games."
As Hollinger himself points out every so often, season after season the best teams in the NBA have so-so records in close games, but over the course of the season, build up their records with easy victories. In a close game, one lucky or unlucky bounce can make the difference...and luck does happen in basketball.
Look at that Miami-Lakers game the other day. Down 2, Kobe shoots a fadeaway, it's halfway down, rings around at least once, and somehow comes out. Does that show that Kobe and the Lakers don't have what it takes? Does that really prove that Miami knows how to close games? I mean Kobe got the shot he wanted and nearly hit it. One slightly different variation of luck, and suddenly it proves that the Lakers are the ones with the grit to close out tough games? Close games are exciting and often decide the season in the playoffs, but they really tell you very little about what to expect from a team in general.
I know this post won't do any good, but considering that season after season there is little to no correlation between a team's record in close games and playoff success/overall record maybe it's time to stop putting too much stock in winning close games as a measure of a good team.
