British fighters are no more protected than they were many years ago or most other countries. As has been said, the aim is to maximise the income of the fighter, and then try and achieve things in that order. Fighters will eventually find their level in the end but ability (think Galzaghe or Naz), age (think Froch), ring wars (think Froch again) and ambition (think Hatton leaving Warren) are factors that influence how far they progress.
