Way I predict RCB progress:
18 May - Bangalore vs CSK. Away. Lose
20 May - Bangalore vs Hyderabad. Away. Win.
22 May - Bangalore vs Kolkata. Away. Win.
24 May - Bangalore vs CSK. Home. Win.
14 points.
RCB need to win more matches than KKR and Hyderabad (also 4 games left) or win by huge margins to have NRR on their side.
