12. Lewis Hamilton
Hamilton makes this list for one of the strangest reasons. Unlike some of the other athletes, he didn’t threaten to leave or demand a trade. But he created a problem for Mercedes at the Miami Grand Prix because he wanted to wear his distinctive jewelry (via NBC Sports).

The FIA decided to enforce a ban on non-regulatory jewelry and clothing items. They only allowed exceptions for nose piercings and wedding rings. Hamilton said that he wouldn’t race unless they softened their rigid stance. In the end, he got his way and wore his bling.
