As Luke Kornet gets ready to don the San Antonio Spurs' black and silver in jersey No. 7, he couldn’t resist cracking a joke about the legendary big man who once wore No. 21 in San Antonio.

Luke Kornet was one of San Antonio's top free agent additions this offseason, and he's already saying all the right things for the fan base.

Luke Kornet has been known to have a sense of humor. And that carried over from Boston to San Antonio. Kornet was asked why he chose to wear No. 7 with the Spurs, to which he said he “hoped to be a third of the player Tim Duncan was,” via Spurs reporter Matthew Tynan. Duncan, who spent his entire 19-year career with the Spurs, wore No. 21.
