It has been intriguing to me as to how one becomes a Cricket Commentator in India on par with,
Tony Cosier,
John Arlott,
Harsha Bhogle,
Jack Fingleton,
Robin Jackman and the likes?
Well , you should have played Nine International Matches.
You have the capacity to advise Sachin Tendulkar,Rahul Dravid,Brian Lara, Ricky Ponting on Batting, Anil Kumble,Shane Warne,Muttiah Muraidharan,Allan Donald in Bowling,Suresh raina, Yuvraj Singh and the likes in Fielding.
And you should know how to speak Queens English Like ‘He got to have it, He ought to have hit’
More importantly,

Your Cricket Career should read as,

And you must have the modesty to reply to Sunil Gavaskar when he asks.you,

I’ve said before — again and again, in fact — that I don’t like Siva.
My animus boils down to one big thing: Siva comes across as a person impersonating a commentator, rather than an actual commentator. He knows the textbook things to say, and he dutifully says it, but that doesn’t necessarily make for good television. Ravi Shastri, for instance, understands the dynamics of drama — “Now this should be interesting!” — and he knows how to manipulate his voice and tone appropriately.
