I was out there too and also did not see any fights - there were more weirdo "Superfan" people than I thought.
I was on the upper deck and it was nice to watch from a different view than TV. Seems like we run very few routes in the middle of the field in about the 10-15 yd range, other than Kelce hanging out there sometimes. When we did have guys there, they were frequently open and ignored. I think Mahomes and the offense need a little more Alex Smith in them. The D played great but was a mess on the TD play. They weren't fully lined up and should've used a timeout to get their crap together. It was fun to watch Mathieu line up in one area and then, before the ball was snapped, sprint to the other side of the field and be perfectly positioned to blow up the play. It happened multiple times and is something that I don't feel like is clearly conveyed on TV. I do think some of it was the benefit of playing against an inexperienced QB.
