I do think most of us can agree that Tua deserves another year because the O-Line isn’t getting worse, we’ll have a new head coach, and we’ll hopefully invest in a WR or two opposite Waddle and Parker (if he stays), and a young power RB to pair with whoever stays of Lindsay, Duke and Gaskin.
I think what many are upset about with Tua is that while he has shown the ability to partially offset all of the above with quick passes and decision making, he hasn’t shown the athletic ability of most other QBs in the NFL which makes his upside lower. Once he has his offensive support in place next year (God willing), then we can see if he can be more like a Drew Brees and less like a Matt Moore.
