Let's see...
-Aerial Assist was a great game dogged by implementation details. I don't think we have to elaborate further on refs, missed assists, fouls, and the like.
-FIRST really needs to put signs up at the key venue entrances: "Come on in! No reserved seating." It was better this year than most, but at crowded venues it's still an issue.
-While we're talking signs, signs pointing teams to the proper sections for Championship fields would be nice. I still have to peep into the seating portals to get my bearings, and I've gone all four years it's been in St. Louis.
-No free corn dogs!

-Championship inspection time on Wednesday felt all too brief, but then we were making some significant improvements. Grain of salt there.
-Maybe not a hard negative, but in 2014 we're getting awful used to smartphones. I'd love to see FIRST adopt Spyder or Megaphone (or both!) and get them a better pipeline for data. Or better, get that pipeline out to students to create better ways to display the data.
-I heard mild frustrations over the inspection spec from others, though we weren't as affected. I do think "inflated to size not pressure" as in other years is a better way to go.
-The fewer things that go "to the booth" for rulings from Manchester, the better. It seems like those calls tend to have the worst outcomes (though I may have a skewed sample).
I'm sure some other things will hit me when I've had a full night's sleep, but these are what come to mind right now.
