Yeah the team could get too cocky, but getting punched in the mouth isn't always a bad thing, it about how you respond to it.
But yes, the Falcons (whom learned the wide zone under LaFleaur when both were with the Titans and then followed LaFleaur as Titans offensive coordinator) will stay extremely committed to the run game and will absolutely try to pound the rock down the Packers throat.
Falcons had 18 passes to 26 runs in week 1.
They have invested heavily in draft picks to their offense, but their defense has been crap, this off-season they hired the Saints DL coach and brought in a bunch of vet FAs from Saints, Titans and elsewhere to help the defense.
It'll be interesting to see how Packers run defense holds up, and how the Falcons new defensive looks. Also they got coach Jerry Gray, whom knows a thing or two about the Packers.
One thing I noticed (and this is partly scheme based), is Love is hitting those check downs hot and heavy, which he should be in this scheme, but Rodgers didn't exactly do that.
But also the Packers did not seem to be on the same page with the deep balls, too often, the ball and intended receivers were not going to the same exact spot. So in theory, if a team tries to take away all the short spots, and dares the Packers to beat them deep, that could be an issue, at least until they get in the same page.
