Not so sure about Dawson...he has only avoided Diancou and the reasons for that seem evident. Lately Zsolt Erdei has been fighting trash but his early resume has some alright names. Not sure if it so much him being protected, more probably him being so hard to market and he isnt an attractive target for the bigger names around him.
Ronald Hearns EDIT He's fighting guys with better records now. I just remember seeing him fight bums who flopped against him.
He was only protected from fighting Calzaghe and you could argue that JC never really tried hard to make the fight. Apart from JC who else was Sven protected from?
Sven Ottke - the most protected and the most BORING fighter ever, every time I saw him I wanted to throw up.
