When Minnesota Timberwolves star Karl-Anthony Towns called himself the greatest shooting big man of all time, it raised more than a few eyebrows. After all, it seems he is forgetting and disrespecting the players who have accomplished a lot before him–like Dallas Mavericks legend Dirk Nowitzki.

Nowitzki, for his part, has heard the proclamation and didn't take any offense from it. However, he believes it is too early for the Timberwolves big man to make a claim for such title this early in his career.

During Tuesday's game between the Mavs and Timberwolves, Dirk shared his take on the matter as he served as a TV analyst for the broadcast of the contest.

“He's got the confidence and that swag — that's what you need to make it in this league. Not sure if he's the greatest of all time already, he's got a long way to go. But I mean, his touch is great and he's got the full package, so definitely if he keeps playing like this, he's gonna be up there before his career is over,” Nowitzki said of Towns' GOTA claim.

It's a real class act from Dirk Nowitzki, and he got a valid point.

While Karl-Anthony Towns undoubtedly has the tools and skills to become the greatest shooting big man of all time, he has to let his game and achievements do the talking. He has only made the playoffs once in his career, and if he wants to be in contention among the best in NBA history, he has to do a lot more than score buckets with long-range bombs.

Being the GOAT at something isn't a title one can just claim. Of course, one needs to have that confidence, but at the end of the day, what's important is how he backs it up and walk the talk. The Mavs icon can certainly give him some tips about that.
