None of these will be going to happenThe best model I would suggest is
1. 11 IPL teams from 2021 onwards
2. All players go into auction poll.
3. No Retaining or Right-to-Match in the auction for 2021.
4. After 2021, only Right-to-match to be allowed. No retaining
5. Each team plays the other once. So 5 home games and 5 away games
6. Max 5 foreigners allowed
7. 1 foreign player compulsorily from the lesser known nations
8. No more toss - Away team gets to decide what they want to do
9. Bonus point system for big margin wins
