My understanding is that a bot team will promote but then be immediately replaced by the team with the best record in Div. II. In order these would be:
1) The Cows,
2) Le Grand Cox
3) Plateaus
4) Mumbai Indians (on point differential).
Iran Proud is the only non-bot team in II.3 so they are guaranteed promotion which leaves three slots open. If the Mumbai Indians defeat The Cows (they lost by 20 last time), they will go through and the Plateaus will not. Otherwise, it will be the first 3.
Of course, this depends also on whether any of the bot teams survive their relegation series. If they do, then all four of us will go through. There could also be an unexpected surprise in the playoffs. I only beat the Yaduers by 10, whereas I had expected to win by 20!
