Nowitzki leaps at another opportunity to make fun of his regression

Nobody loves roasting Dirk Nowitzki more than the man himself.

The Dallas Mavericks star takes such great delight in poking fun of his advanced age and deteriorating mobility, even a tweet about a video-game bug can prompt some lighthearted self-slander.

Apparently, the older he gets, the more he tweets about slowing down.

Nowitzki is coming off a season in which he recorded 14.2 points, 6.5 rebounds, and 1.5 assists per game, which are all below his career averages. He's a week away from his 39th birthday and will enter his 20th NBA campaign in 2017-18.
