3. James Simpson-Daniel
The Gloucester legend was always a fan favourite and narrowly missed out on selection for the 2003 World Cup, despite being involved in the all-conquering England team that dominated in the southern hemisphere during the 2002 Autumn Internationals.
Although heralded as a potential world-class wing, injury constantly blighted his career and numerous England head coaches looked to other options ahead of him. He ended his career with a pitiful 10 caps, but it could have and should have been so much more.
