Here is a part of the McDermott hire that gives more fuel to the "Pegula got lucky" theory:
There are reports that they hired a search firm when they hired Rex Ryan and they suggested that they hire McDermott. Pegula was entranced by Rex Ryan in his face to face interview and hired him.
When Rex didn't work out, they hired the same search firm, they once again suggested McDermott, and the Pegulas listened that time.
If that is how it played out...
So a dufus who is easily bamboozled by blather, bluster and bullshit.
