I don’t think enough credit is being given to innovations on defense over the years. Coverages and pressure packages have gotten increasingly complex over the last 10 years, let alone the last 20 years. It’s harder for a young guy to come in and understand what the hell is going on than it was when Brady was first starting. Motion counters some of these complexities but necessarily takes time to execute and therefore doesn’t leave a lot of time for the QB to make changes. That’s the kind of stuff Brady is talking about but I think the success of the Shannahan/McVay offenses relative to other offenses says that this is still better than expecting these young QBs to have perfect mental models of everything going on.

Man they really called the same screen 3 times in a row
