How can RCB make it to League stage?

After the loss against Cape Cobras, it is not all over for RCB.They are still in a race to League stage.
Let's see how it can work out-

• There are 4 groups with 3 teams each.In Group stage, every team plays 1 match against the teams in it's group.
• 2 out of the 3 teams in each group will go ahead to League stage.

For RCB, it is a must-win game against Otago.If RCB beats Otago and

• if Otago loses against Cobras too, they are out.
• if Otago beats Cobras, all the three teams will carry 2 points each and NRR (Net Run Rate) will come into play.

So, the conclusion is- RCB should beat Otago comprehensively to fix their spot in League stage.
