i don't think it's a black thing or shit, it show how the vince's head is working.
Something like " hey ron i know you're a former NWA champion, but you're in the WWE now and we don't give a flying fuck at your past accomplishments boy, now go to the ring and make The Great Khali look good"
that's why you'll never see AJ Styles or Christopher " Fallen Angel" Daniels in a WWE ring
