End of the day, it's not about Rattler vs. Carr when thinking about cutting him, it's about the long term structure of the Saints and getting to a playoff window as soon as possible.
That's true for some people, but it's not true for others.
I think the quickest path to a playoff window is with Carr or an even better QB with experience. We shall soon find out what Moore thinks, because the Saints and Moore will be shooting for the playoffs this year. They aren't going to take a mulligan for this year.
