NBA video: Matthew Dellavedova in hilarious height mismatch with Dallas Mavericks giant Dirk Nowitzki

WATCH as Australian NBA star Matthew Dellavedova shows the world how NOT to defend 2.13m giant Dirk Nowitzki.

Matthew Dellavedova was hopelessly mismatches against Dallas giant Dirk Nowitzki.

WHAT does a 20cm height advantage in the NBA look like?

This.

Aussie Matthew Dellavedova showed no fear when he marked Dallas Mavericks’ legend Dirk Nowitzki during today’s pre-season game in Cleveland.

Nowitzki, who stands at a towering 2.13 metres, moved both his arms over the shoulders over his 1.93m opponent in what must be one of the most exaggerated fakes of all-time.

US website Yarbarker called it the funniest moment of the NBA pre-season.

Social media agreed.

And Dellavedova stands about 2 inches taller than me. Dirk is huge.
