Fisher has had same philosophy forever. I can see him now ”We need to keep playing the same way just better more execution ”
Fish once had a dynamic QB in Air McNair, a guy who could rumble like a FB, air the ball out with the best of them, and generally be a game changer himself. In TGII, Fish has an 'Eddie George on steroids', but he has had nothing close to the dynamism that McNair strutted so effortlessly. That McNair-led Titan team seriously stretched us in our Super Bowl win. We can be sure that Fish knows his QB's and offensive coaching are lacking some important traits.
Hell, a guy like Case with a strong arm, accuracy, and vision can galvanize our offense along with TGII. We don't really need a game changing QB (although I will certainly not complain if we manage to snare one)---just a competent game manager.
Snaring a coach who can develop a passing game to effectively complement the running game and provide intelligent input on adding QB options would be a seriously positive acquisition.
