How does the Draft order and Draft Lottery work?

Each spring, a lottery – comprised of ping-pong balls drawn randomly in an audited event – decides the fate of the 14 teams who did not qualify for the Playoffs. The teams with the fewest wins have the greatest chance at winning the Lottery. Three Lotto balls are drawn, deciding the first, second and third picks. After that point, the remaining picks go sequentially, in order of lowest finish to highest finish in the standings. After pick No. 14, the teams choose in reverse order of regular season finish (the team with the best record goes last). Teams may move up and down in the order with trades.
