Offense with some early struggles coupled with some sloppy play.
You can see that Manning at times isn't as quick to diagnose stuff as Ewers would have been and it's an example of how he isn't quite ready to start. He isn't bad by any means, but he's inexperienced and it's showed the last 2 weeks.
Although, the score makes it look worse than it's actually been being as they have been able to move the ball quite a bit. RB Jaydon Blue fumbling in the red zone and Cook dropping a wide open 65-yard touchdown didn't help.
