I remember this happening at the time and it came up at a bar trivia night recently and got curious. For context Nance Sr wore number 22 for the Cavs and got it retired - When Nance Jr got traded to the cavs, the NBA gave an exemption and allowed Nance Jr to wear his dad’s number.
And before somebody says “Bronny and Lebron”, two players can’t wear the same number so that’ll probably be the only time ever somebody doesn’t get this because their dad is still playing
That’s pretty specific fact to have a similarity, but there were instances
When fighting Cell, Piccolo allowed Gohan to wear his traditional Namekian battle attire, with cape and everything.
