I doubt it. I do think Glenn was the first choice, but there are others on the list and McCarthy became the likely 2nd choice if Glenn goes to the Jets.
He was the last added to the list because he could only be put on the list once he left the Cowboys. And I suspect that Chicago was McCarthy's first choice so he wasn't going to bother interviewing here until the Chicago job was off the table.
I really don't think Rizzi is going to get the job, but I'll eat crow if he does.
