The Pats are okay as long as Brady is still playing. It's not often you replace a great QB with another great QB. Sure the Packers struck gold going from Farve to Rodgers and the Niners from the GOAT to Steve Young, but ain't gonna happen for the Pats. Garapolo ain't the QB they're looking for.
Pats already did it, going from Bledsoe to Brady.
