Lots of people still use land lines for phones, does not make it wrong, but it is an antiquated.
Also the lottery that use balls are much cleaner. If you still want to use the little balls then simply use 15 balls if you finish last 14 if you finish 2nd to last 13 for next and so on. Team logo on each.
For the first pick ball pops up, take 30 seconds to remove any other balls, then do the next and so on. Do all 15 teams, make it a true lottery. Or you can stop after 3
And my whole point has been remove the curtain, I don't believe it is rigged, but there is an easy way to eliminate these things.
