Mike McCarthy didn’t garner the interest from Saints that he anticipated and taking a year off; McCarthy backs out as a result of Moore being in lead

The Saints have offered Kellen Moore and he's accepted. They cannot officially announce it until the Super Bowl is over. That is the only actual explanation for all of the other potential Saints candidates dropping out like Thanos snapped. If all these guys are pulling out and Moore hasn't unofficially officially accepted the job, then YIKES.
