First the 2018 league table:
And the corresponding tables of 2015, 2016 and 2017 (in that order):
Note that the 2018 table shows a slight departure from the past. From 2015 to 2017, 16 points was a clear demarcator for qualifying for the playoff rounds. In 2018 RR has qualified with 14 points.
Does the position in the league table give a clear indication of the final winner?
In 2015: Winner MI (2nd in league), runners-up CSK (1st)
In 2016: Winner RCB (2nd), runners-up SRH (3rd)
In 2017: Winner MI (1st), runners-up RPS (2nd)
We see that in recent history the 2nd-ranked team in the league has slightly better chances – so CSK can be said to be the favourite (if one is superstitious).
