Leon and Michael Spinks
The boxing world has its fair share of famous siblings and we can’t leave out the Spinks brother. Leon Spinks was one of the few fighters to actually beat Muhammad Ali in a title fight. Michael Spinks is one of the most respected fighters in the history of the sport. Still, most people remember the Spinks brothers for losing high profile fights against Ali (rematch for Leon) and young Tyson.
Vernon and Vontae Davis
Vernon Davis was an elite tight end for years with the San Francisco 49ers. Vontae Davis spent the bulk of his career as a shutdown corner with the Indianapolis Colts. Both players are still competing in the NFL. You’d never know they were related due to their size disparity: Vernon is 6’3 while Vontae is 5’11.
