The Dallas Mavericks have gone through every possible phase an organization can in a 20-year period. Since the 1998-99 season, the Mavs went from a bottom-feeding team in the West to championship contenders in the mid-2000s and NBA Champions in 2011, but have slowly climbed back down to the lottery since. The one constant in those 20 seasons has been Dirk Nowitzki.

Earlier this summer, Dirk Nowitzki agreed to a one-year deal to return to the Mavs, and was administered an offseason drug test on Saturday afternoon. His response was absolutely hilarious.

“Did you see me move last year??” Nowitzki told the guy doing his test. “If I was on something, I need to change that product ASAP!!!”

At this point in his career, Nowitzki is nothing more than a backup power forward who, at most, will play around 25-28 minutes per game. The Mavs are really insistent on preserving Nowitzki, who underwent ankle surgery at the end of last season, and not playing him heavy minutes. In the past couple of years, the Mavs haven't played for anything other than a lottery pick, but that could change after their big offseason in drafting Luka Doncic and signing DeAndre Jordan in free agency.

In the 2017-18 season, the 20th of his career, Nowitzki averaged 12 points, 5.7 rebounds, 1.6 assists, and 1.8 three-poiners per game on 45.6 percent shooting from the field and 41 percent from beyond the arc.
