5. Gavin Henson
The man who tackled Tait. Despite two Six Nations winner’s medals, Henson falls firmly into the category of those that failed to fulfill their potential.
But despite his love for hobnobbing with C-list celebrities, appearing on reality TV shows and bottled tan, all of which seemed to take precedence over his rugby, Henson actually didn’t have that bad a career.
He’s now playign rugby league for running a pub back in Wales.
