I don't think Tito will be as tough as Randy Couture since after I saw UFC 44 I will always believe Couture will and still possibly can dominate Ortiz. How did Ortiz not get stopped in that fight? That was insane.
Around that time Randy dominated Chuck as well. The second time Chuck fought Randy he had aged and was not the same fighter as he was when he beat Chuck and Tito. It would be the same if Tito fought Couture now.
