When you go through quarterback stats for the first half of 2022, you’ll find Jimmy Garoppolo in the top-10 of seemingly every category. Then, when you filter those same stats from the time Brock Purdy became the starter, it’s nearly identical.
There are a couple of takeaways here. First, Kyle Shanahan does an incredible job of doing the heavy-lifting for whoever is under center before the ball is snapped, mostly by using multiple pre-snap motions and window dressing. That’s why post-snap, generally speaking, whoever the intended target is doesn’t have a defender within two yards of him.
Brock performing comparatively to Jimmy in his first half season of starts is beyond admirable; it’s impressive.
