#4. Sam Burgess

The flanker/centre (we’re still not sure) didn’t just regret his transfer to Bath but his transfer to the sport.

He was signed by the Blue, Black and Whites on a three-year contract, starting from October 2014.

Just 12 months later, following his involvement in England’s embarrassing Rugby World Cup campaign, he left the sport and Bath, opting to return to South Sydney Rabbitohs, signing a three-year contract, approximately worth $1.5m AUD per season.
