My issue is that it is way too complicated. Just give each team one ball, put it in the mixer, and draw, live, in front of everyone. Any other way it opens the door for people to question it, especially with it taking place behind closed doors.
How could anyone not think that there have ever been ANY shenanigans taking place? We already know the dirty ref TD screwed the Sac Kings vs the Lakers. We knew that game was BS at the time and years later it was confirmed. I wouldn't be shocked if there was a lot more of that going on over the years. It is what it is.
