Is this a thing that happens to all NFL teams? Is it human nature to relax, or is it the prevent defense and the conservative playcalling?

I get, to some extent, backing off on defense so you don't get burned for a quick touchdown. But wait, didn't that happen anyway? It wasn't until the end of the game, when Dom went back to a more aggressive defense and MM let Rodgers throw that slant to Adams, that they salted it away.

That second half kinda took some of the joy out of that game.
