Baltimore Ravens QB Lamar Jackson will not unseat QB Joe Flacco as the team’s starter in 2018, according to head coach John Harbaugh. ‘Joe Flacco is our quarterback, and that’s the thing that you’ve got to remember. Lamar’s gonna have a great chance to develop. I think you get to this stage in a quarterback’s career, you see it done in New England and you’ve seen it done in a lot of places,’ Harbaugh said.
