Jets goal is to keep Glenn from leaving the building [Multiple HC & GM Candidates tells ESPN’s Cimini all indications point to Glenn]

It’s the other way around. He apparently left the jets without a contract. That’s tough to do, that’s why car salesman are so abrasive because they know once you leave, the % sale success drops substantially

He might decide to do the Saints 2nd interview if the flights clear up from the weather. But it appears that he’s likely headed to the Jets according to reports after he finished the Jets interview.
