#1. Correct. Nobody is perfect. But some qbs are closer to perfect, or “better” than others. No qb throws a perfect ball every time, but some qbs throw the ball better and at a higher velocity and more accurate than others.
#2 correct. It does not guarantee success, but it INCREASES your odds of success. This is why the QB is the most coveted and highly paid position. To start a franchise, you first need a franchise qb.
You are missing the point, every qb gets criticized. Aikman and staubach were too, but some qbs are criticized and critiqued less frequently than others. We want a qb that can throw the ball with a tight spiral and hit moving targets on time and sees and reads the defense correctly.
We want a qb that elevates the receivers.
Romo made Dez, Austin, Crayton, and Laurent Robinson millionaires.
Dak just makes receivers unemployed.
