Isidro Rodriquez in the Eder Gonzalez vs Juan M Coggi 1 was the worst I've ever seen, live or recorded hands down. Have a look if you can, it was literally criminal in every way...from holding a fighter up in his corner so he could be revived to ending rounds early etc etc.

He was banned for life and think only worked a single fight 4 years later on appeal or something.

Ralph Condunt (?) was bad. Randy Neuman too. The poor ol guy working Antonio Tarver vs Eric harding 2 almost got Harding 86'd and to the point of Tarver literally yelling in his face to stop the fight.

And oh yeh...then there is "Its all about ME, I'M fair but I'M firm" Joe Cortez.
