Why are the brothers, the ex black NBA players in the most cases such haters of Jokic and the white Euro players in general

Is it pride, some white players being better than the black players, racism ,xenophobia etc. I am trying to solve the riddle

The man in this video, the ex NBA player and five time all star is claiming that Jokic wouldn't even made it to the roster of any NBA team in the 70"s, even in the league full of plumbers and electricians. Then he gave the comparison of the certain white players who played college and NBA back then to Jokic, who were the scarabs in his words and judging by his description of those players I wonder if this old dude have ever watched Jokic playing the basketball??? Why would he singled out the player with the most translatable game to any basketball era and not some of the black players who clearly don't have the skills, like back to the basket game which was predominant in the 70"s
