Well it's not like he fought the bigger echelon HW like JLB, Hunt or Sem Schilt.
The people he fought must not have much " muscle mass" advantage ( I remember him being between 96-100 for these fights ) and most of those opponents save Goodridge and Mighty Mo ( who aren't exctly the most skillful ) would fight in the -100 kg ( if it wasn't already the case ) nowadays..
He did survive fights with Aerts, Glaube Feitosa, Ruslan Karaev, Goodridge and Mo without getting KTFO and that alone is commandable.. and I don't even like him..
All I remember about him careerwise is that pathetic circus fight against a 46 years old Don Wilson in full contact rules...
