but I doubt Mullen was offered the job immediately when all this went down. It would make more sense for Foley to step back, put some thought into the hire, and contact some agents to gauge interest of top candidates.
Just like when Petersen accepted the job at State and then changed his mind, only a few people know that for sure and it will never be a matter of public record. The public rarely knows when an actual offer is made from a school to a coach, and the only info out there is what an agent might leak to the media. And you cant trust that info because they are always trying to make their clients look as good as possible.
