Someone who knows Casserly, speaking on the condition of anonymity, said Casserly has been raving about Marrone since he was the Syracuse coach (2009-12). Even then, Casserly was describing Marrone as a future NFL head coach, a rising star in the business.
"He was totally infatuated with him," the person said. "You have to know Charley: When he gets on something, he's a pit bull. I know he's got Woody [Johnson] all lathered up."
Johnson is familiar with Marrone, who was the Jets' offensive line coach from 2002 to 2005.
This much we know: The Jets are interested in Marrone, who opted out of his Bills contract Wednesday night, and they will try to schedule an interview if they haven't done so already.
Casserly and Ron Wolf, both former longtime general managers in the NFL, are working as consultants for the Jets. The team has already conducted one interview (Jets running backs coach Anthony Lynn), and they have at least two more scheduled, both with Seattle Seahawks assistants -- defensive coordinator Dan Quinn and offensive line coach Tom Cable. Those interviews will happen Friday, and perhaps Saturday, in Seattle.
