Why wouldn't you still want him? He'll have had a year off with plenty of time to heal. Plus he's just a few years off of winning the MVP. It's doubtful there's anything better out there unless you want a Ryan Fitzpatrick type of QB. Draft some OL. Draft his replacement within two years.
I expect the 2020 quarterback depth chart to be exactly as it was prior to week one of 2019, barring something completely wild and unlikely, such as Tom Brady and Josh McDaniels deciding to join forces in Carolina.
