There's nothing to lose by adding talent to your quarterback room if you're the Cleveland Browns. Given that Deshaun Watson is out for the entire season, Jameis Winston is a free agent that they may not be able to re-sign, and they're likely to phase Dorian Thompson-Robinson out of the team's future entirely, they can use all the help they can get. More than likely, that help is going to come through free agency. A veteran quarterback to lead the team would be ideal, especially since the team feels they have enough tools to actually be a decent AFC team - they're just missing a franchise signal caller. The other way that help will come is through the draft, and in this mock draft, they take two quarterbacks to fix their issues at the position instead of just one.
