After watching the video, I noticed that while I may notice something, I do not pay attention to every little detail, because I get distracted by something else.
While watching the video, I counted 13 passes and did see the gorilla enter into the shot. But I did not pay attention to what he did or anything. I tried to keep watching the white team pass the ball, but I occasionally would watch the black team, just to see what they were doing.
It is hard to stay completely focused on one thing, but I did pretty well, in my opinion.
