They are witnessing the drawing. One would think they would yell bloody murder if they thought their team was getting the shaft.
But again, what are they actually seeing? Stuff being put in a hopper, and one being taken out. Do they get to examine everything going into the hopper? The hopper itself? Remember the bent card for Ewing’s draft, was that an accident or a rig? Why didn’t any of the witnesses yell bloody murder? And there have been team presidents complaining about lottery results in the past.
The results could be a coincidence, that’s the fun part about random events they actually can break the “desired” way, but there sure are a lot of these highly convenient coincidences.
