There went your preseason preconceptions! Trey Lance? Ugh. Carson Wentz? What the... And Patrick Mahomes was juuust right, like Goldilocks's third bowl of oatmeal.
My bird's eye view of Week 1 is to not read into it too much. For example, the aforementioned Wentz had a bunch nice throws with good decision-making, but he was Wentzian at times with two interceptions and a few more forced throws that could've gone poorly. Or the previously mentioned Lance did struggle to execute, played with happy feet too often but he also showed off his arm with a handful of excellent throws and I'm willing to give him a pass based on Chicago's rough weather and sloppy field. There are two sides, at least, to every player's performance and we shouldn't form too many firm opinions just yet.
