I’m not advocating for either but you’re ignoring the fact that there’s very little financial risk with either Murray or Cousins beyond 2026. Most of their guaranteed money has been paid already by their incumbent franchise and there’s not much owed after 2026 if the Jets make a move for one and want to move on.
Go back and look at what Mills actually did this year dude. He was horrible against Buffalo and Denver. He played well against the hapless Titans although the offensive barely scored and to his credit had a good game against the Jaguars. He’s not worth anything more than a 5th round draft pick if that and he’s wildly overrated here.
