mario is far from slow. Dareus and Wilkiams are both really quick for big men. As is Suh. Don't forget you still have Rivers, Spikes, Lawson and Hughes in blitzing situations.
Not to mention, our biggest weakness was run defense. Tell me how you defend against that front 4. And add in Kiko and Spikes to the LB level. Unstoppable. Gilmore island with Aaron Williams backing up the other side. I'd say were good to go.
that would be considering he wouldn't take a pay cut to stick with Schwartz.
