Sure it's debatable. And objectively, the rest of the NFCS division is worse than the rest of the AFCE. Not to mention the AFC overall where QBs rule that conference. If I'm Carr, I want the best odds of getting to the playoffs, and the Saints have better odds than the Jets on that point.
That said, the Jets probably do have more money. The question I guess is whether that's enough to sway Carr their way.
