Michael and Marcus Vick
Michael Vick is one of the most controversial athletes of all time thanks to his imprisonment for dog fight. Marcus, Michael’s younger brother, was another young NFL player who watched his potential drain away due to off field issues. Marcus was kicked off of Virginia Tech for his numerous issues. Marcus would end up playing one game in his NFL career back in 2006 for the Miami Dolphins. Marcus would never touch the ball in the NFL.
Hank and Tommie Aaron
Hank Aaron is MLB royalty and, at one point, the leader in MLB history in home runs. Tommie Aaron, on the other hand, could barely keep himself in the league. Hank and Tommie were famously the first brothers to appear in a League Championship series while on the same roster. Tommie would hit 13 home runs in his career while Hank would hit 755.
