The NBA provides a higher standard for success and offers more extreme examples of terrible than will be found in North America's other three primary men's professional team sports.
The reason for this is mathematical. An NHL team getting to four goals is going to win 90% of the time. A major league baseball team getting to five runs is going to win 85% of the time. An NFL team that scores three touchdowns, kicks a couple of field goals and scores 27 points is going to win 75% of the time.
NBA teams are now playing to 115 points to get a victory. The winners are going to need 40-some field goals, twos or threes, to get there.
It has been an annual ritual when the "winter sports," the NHL and the NBA, get to mid-April and start conducting playoffs:
The seedings get twisted upside down in the first couple of rounds of the NHL tournament. Almost never do we get a major upset in the first two rounds of the NBA playoffs.
You can analyze this extensively, but it's simple: When you play to four goals (or three in the playoffs), the team with the best players is one late-in-game carom from getting beat. When you play to 40 field goals, it is unlikely the best team is going to be done in by caroms often enough to lose four times in seven games.
Simply reaching the playoffs creates possibilities in hockey, football and baseball (insert your Twins one-liner here). That's not the case in the NBA.
Squeezing into the bottom of the playoffs is such a no-hope situation in the NBA that the Timberwolves have done so once since 2004, and we're still mad at the coach for getting them there.
