Here is my two cents in how the NBA should fix the lottery system and make end of the season basketball for those losing teams MORE EXCITING!
Many such as Simmons among others have suggested having a playoff for the 8th spot in the playoffs amongst the lottery bound teams. Thats a good idea in itself that I would like to use to determine the Lottery System. We could start out with our currently lottery system where each team gets a certain amount of lottery balls based on their W-L record, the team with the worst record getting the most lottery balls and thus the highest probability of landing the #1 draft pick. The NBA can host a single elimination tourament like March Madness with the ultimate prize of landing more lottery balls (for now I'd suggested an increase of 10% chance of landing the top pick) to the team who wins the tourament. Of course, the home team advantage goes to the team with the better record.
Therefore, the team with the worst record, such as the Nets this season, still have a good chance of landing the #1 draft pick based on their horrible W-L record, but a team that is doing decently but won't make playoffs like the Hornets, can possibility raise their draft positions by winning this tournament so that they won't forever be stuck in mediocrity as well. I think this can make basketball infinitely more exciting for those losing teams in late March to April and have a chance for those perinally losing teams like us Clippers get a chance to see "playoff" basketball for once!
Tell me what you guys think and any additions you'll like to make.
