"Will get done" is not definitive. An actual signing or dissolving of their professional relationship (e.g. trade, waiver, etc.) is definitive.
What I or anyone else says or speculates about the contract negotiations is entirely irrelevant. The only relevant thing is what has not yet happened. That said, I have stated since 2016 Jones had completely committed to Prescott and that he would sign Prescott a franchise quarterback level contract eventually. My personal expectation is that an agreement would have been done already. It has not but that is my problem, not Jones or Prescott's.
