#6 Joe Koff

Who is he? A Sinclair broadcasting executive assigned to Ring of Honor as the Chief Operating Officer and Vice President of Talent and Development.
What makes him an influencer? While rarely seen on ROH television, and even more rarely referenced in storylines, Koff is a long time television executive who has many years of experience in the industry. He pushed hard for, and won, a prestigious spot at Madison Square Garden for ROH's joint show with New Japan in 2019.
Joe Koff isn't exactly a man you see much on television. In fact, he is rarely referred to in any capacity at all by the promotion, because most of his work is done backstage--though he does seem to be taking an active role in Christopher Daniels's most recent 'win or go home' angle. Basically, the angle is Koff is refusing to re-sign Daniels because of the Almighty one's age and Daniels must win the ROH world title in order to keep working for the company.
Koff has recently stepped up his game, booking Madison Square Garden after some political maneuvering from the WWE tried to prevent it. Now looking forward to an opportunity to compete with WWE on a grand scale, Koff will be a major influencer in 2019.
