[Alan Anderson]

I didn't intend for this to be a complaint, or even much of an issue. The red-side volunteers' theory seemed at least plausible, and I was just wondering what other people saw at the time.

I myself only saw a couple of matches from the blue end of the field, and I wasn't closely watching the placement of out-of-bounds balls. I could easily have missed seeing any being put in the bag, since most of the volunteers were good at being unobtrusive to the point of near-invisibility. I only noticed the ref at the corner dropping balls onto the field because he was in my direct line of sight to the action.

(I did think it odd that he had his back to the robots for several seconds each time he turned to motion for a ball to be thrown to him, but I don't want that observation to be construed as a post facto complaint either.)
