I remember first watching the Payton-Marrone-Brees blocking scheme. The tackles were pushing the defensive ends way out wide, which worried me because wide is also where the DEs want to go, but the key to it working involved the tackles staying within themselves and not letting pass rushers win on their second move. The interior linemen just had to not get beat so Brees could step into space and make the throw. He was so good at finding the sight lines and making things happen, instead of any of the other less-preferred outcomes like relying on extremely deep drops or a high volume of rollouts, or having lots of passes knocked down at the line.
