As far as 2019 is concerned, count Joe Staley in. The San Francisco 49ers left tackle told Chris Biderman he will at least be back in 2019, the final year of his contract with the San Francisco 49ers. Staley restructured his deal in 2017, jumping his salary from $11 million to $17.4 million.
What happens after 2019 is up to Staley. There are no plans for 2020 at least not yet.
Since his drafting, Staley played lights out all the way into the twilight of his career, making it to No.
