Well I agree the video doesn't prove anything. Would need to see a more controlled study. At minimum I would like to see what that line does without any sweeping. If you watch closely you can see the sweeping appears to cause the rock to change handles multiple times, which would explain the straight draw shot. I mean, I've played on some very straight ice before, but never that straight, unless there was a problem with the ice itself. Even the straightest ice moves a couple rock widths on a draw. There are some shenanigans going on, not necessarily with the brooms.
