I think Fedor was used to a ring and did not train in a cage.
To be more successful his team has to plug that weakness.
He trained years in the Netherlands and speaks good English.
If he had come straight over when Pride folded its pretty much old man Randy who he most likely would have obliterated, Gonzaga, Nog who he already beat and Mir. I think he would have had a good shot at becoming champ vs that field.
A few years later vs prime Cain and JDS? he’d have gotten fucked up. The Brock fight would have been interesting though.
Dana White claimed that Fedor was scared of fighting Tim Sylvia, who was the reigning UFC heavyweight champion.
Nogeuira immediately beat Sylvia, who was then signed by Strikeforce to face Fedor. Fedor completely humiliated and destroyed Sylvia in under a minute, then beat previous UFC heavyweight champion Alofsky.
