Either we draft a developmental QB that will probably take 2-5 years before he looks decent (everyone QB besides Mendoza is developmental imo), or we swing on a developmental QB that has already been in the league developing for 5 years. Guys like Willis or Trey Lance. If this staff is on their last legs then I doubt they trust their fate solely to a rookie. Although we might end up going with both options.
If Willis signs a 1-2 year deal for 20-25 million there will be ways to cut him after one year without too much damage. If he's really bad we'll be in position to draft his replacement next year.
I see Willis as a 50% cheaper Kyler, with an easier contract to leave, and he's 3 inches taller. Ideally Willis can operate as a game manager in a run first offense while providing good efficiency on deep shots, and running himself to keep the defense off balance.
