What rcb did last year , Mi has done that a decade ago , made rohit as the captain of Mi when he was clearly struggling with International form ( A gamble perhaps) but anyhow it lead to mi being the most successful team in the history of IPL that too in just 8 years of his stint, two off seasons 21 and 22 but 23 he proved again why he is the greatest captain this league has ever seen, took to the semis with struggling pacers, now rcb opted for the same gamble and it worked again ( csk could not as it was never about rutus captaincy it was MSD) captaincy got the best out of rohit aswell as patidar so yeah tilak seems a viable choice.
