If it means that he starts games in 2020... then yeah I think he probably will.
I feel like he actually has a lot of pathways to "starting games" but not necessarily being "the starter":
- If the Titans are really happy with him and I could easily see them signing him to an extension, but still drafting a QB in the first round.
- I could see him being signed by one of the many franchises that will be near the top of the draft to be "the starter" until they spend their first round round pick on a QB.
- I could see a franchise sign Tannehill and also trade for a QB that "disappointed" in 2019 (Trubisky, Rosen, Dalton, Winston, etc).
- Lastly he could initially find a cold market but then sign to be a backup somewhere that could lead to playing time (wherever Newton lands, Pittsburgh, Philly, etc).
