Dirk was having a year for the ages until he played the Warriors in first round of the playoffs.
Although this is a season many Mavericks fans wish they could forget, it obviously merits a spot in this list.
Statistics-wise, this was one of Nowitzki's best seasons. He scored 24.6 points, grabbed 8.9 rebounds, dished 3.4 assists and joined the prestigious 50-40-90 club. In other words, he shot over 50 percent from the field, 40 percent from three and 90 percent from the line over the season.
He's one of only four players in NBA history to be a member of that elite club.
The Mavericks also went 67-15, which is tied for sixth-best all time. Thanks to his incredible stats and Dallas' success, Nowitzki took home MVP honors that year to go along with an All-NBA First Team selection and an All-Star game appearance.
But those were all regular-season achievements. It was the postseason that became a problem.
The Mavericks became the first No. 1 seed in NBA history to lose in the first round since it became a seven-game series.
And in that series loss to the Warriors, Dirk shrank from the spotlight. They hounded him all series, as he shot only 38.3 percent overall, 28.6 percent from deep and 80.0 percent from the line. He also only scored 19.7 points per game.
If we were rating Nowitzki's seasons based on regular-season success, then this one would probably be at the top. But for better or worse, this list incorporates the playoffs into each year.
And Nowitzki was a big reason the Mavericks were a part of one of the biggest upsets in recent NBA history.
So as much as I would like to make this season higher on the list, Dirk himself would tell you that 2006-07 was a failure due to the playoff loss. In light of the that, Dirk's MVP season has to be on the list, but it can't be higher than here.
