Saints Cap Moves: Derek Carr restructured, Erik McCoy restructured; J. Williams released; cap space is at -$8,543,537

So after reading the reports that Kellen wants Carr for this season I started thinking back to the hiring process. Remember when there were reports he didn’t like our QB room or potential QB room? What if during the interview process Loomis is also laying out some of the Saints plans for 2025. And he tells Kellen that they are thinking of releasing Carr and rolling with our young guys plus maybe trying to sign a cheap veteran backup. Kellen hears this and says he doesn’t like it. He wants a veteran QB aka Carr. So it gets reported that he doesn’t like the QB room and everyone just assumes he doesn’t want Carr. When in fact it was the opposite.

Loomis really wants Kellen so he lets him know that they will work towards keeping Carr and Kellen is hired. Pure speculation but it fits all the data and information we now know.
It's possible that's how it happened. What seems very unlikely at this point is that Carr is being forced on Moore or that Moore doesn't really want Carr and is just stuck with him.
