I don't think you can fully blame the fighter BUT he is at fault regardless.
After all it is HIS career and he should def. have a say.

Fighters need to stand up for themselves and if 1 promoter won't do something for them guess what, there's another promoter lined up behind him that will.

Let's be honest here it's not like Erdei's this big draw or anything....
He needs to grow some balls and do something. The guy can and will stay in obscurity as long as he continues down this path.

The bad thing is he's actually a very entertaining fighter when he's on and hes commited. He'll come forward and try to impose himself on his opponents.
