Well, that is my dry humor!
All five of us are sports enthusiasts to a varying degree and the subject of who are the better cricket commentators has cropped up for a brief while. We exchanged some names at that time and here I go now on what makes a good cricket commentator in my book.
My mother used to tell me when I was a kid that, if I can understand a particular thing well I can do it well. I don't know about other things in my life but cricket has been an exception - Very high on understanding (Confidently, not arrogantly) and very poor at playing (again, confidently). I managed to play a few years of very competitive gully cricket and a large part of the games I played are not because of my skills (Sometimes I played because I owned the bat or ball and some other times because we played the game in my backyard and some other times they wanted me to make the numbers and the last cricket match I ever played was because I was printing salary increase letters).
Sure I am not even a below-average cricketer, but by giving my ears to the fellows commentating on cricket for the best part of 22 years now, I think I have a sense for what makes a good cricket commentator for those watching it on TV/Internet (not for those listening it on Radio - thats a completely different art) and here I go - Its not a cookbook for wanna-be commentators though:
Sense of cricket - Obviously, No briner! But, let me delve. It is not about how much you have played or how much you have followed it or how many rules & regulations you know on your fingertips - It is about sensing the state of the match at any point in time and commentating accordingly, it is about resonating with the mood of the audience, it is about filling the audience with things that are not obvious rather than reading whats happening on the field (thats for Radio guys).
A good commentator in a tense battle will build anxiety and leave all of us at the cusp and say no more words. He will fill us with silence for a bit and then take us through the joy ride or pity valley depending on what transpires next ball. 'say no more words' and 'fill us with silence' are the sense of cricket! If you can think of Arun Lal and Laxman Sivaramakrishnan as commentators, you will understand how important this quality is!
Likewise, a Siddhuism will fly well with the audience when they are in good mood but not when they are in sad mood - This fellow did not realize this and soon shown the door! (BTW, he got another door opened for him called 'parliament' and there you are not supposed to talk that resonates with the mood of the nation - If you do so, beware!)
Filling the audience with not so obvious things is an art - it is not about having reams of papers with statistics supplied by Mohandoss Menon. I heard the other day a commentator saying 'that is Sachin's 1001th run in 4th innings of a test match overseas in matches that India lost the toss' - What the heck is he trying to convey, how on earth this interests a spectator?
Sense of Humor - If I can have my way into selecting all commentators, I would give this equal weightage along with sense of cricket. If you are watching cricket on TV, you are watching it for at least 4 hours (T20 game) - 4 hours of only cricket to be heard and seen is boring and you need a bit of fun in between and hence the demand for giving it equal weightage.
Like with any other aspect of life, making fun can be very dangerous and it is a very fine balance to strike and it is not everyone's pint of beer (=cup of tea, for teetotalers). I feel the best way is to make the audience see the funny side of an event in the match (like fielding, bowling or batting) and here synchronization with camera crew becomes extremely important. One other way is to take a poke at fellow commentator in between - who wouldn't want to see two people fighting as long it doesn't hurt us! (pl. do not repeat it till spectators think you guys are having a personal battle out there - Tony Grieg & Geoff Boycott fall in this place)
Best sense of humor is always contextual and spontaneous - anything other than this, people will make out easily.
Language/Vocabulary - It is important but it is not be all. It is important to the extent that you are grammatically correct, you use words that most people will understand (so choose simple ones), you use smaller sentences (David Lloyd is best at this - never more than 5 words) and pronounce them clearly.
Actually in this skill, there more things to learn on 'what not to do' and to my mind Harsha Bogle is the role model (not because he is best at it) - Harsha has great command over vocabulary but more often he tries to project his skill than using it to commentate on the game. He gives us so many adjectives which are OK first few times but later becomes a pain in the ass! He becomes a Shakesphere, Ms. Evangeline (my 5th grade English teacher) and N Ram (The Hindu Chief editor) at some point or the other in every match he commentates on!
I don't know of any one who watches cricket to learn English vocabulary - thats the point. PERIOD.
Before I shut up,
I like several commentators for certain things that they do: Ian Chappell - gives so many not so obvious things, Richie Benaud - uses silence very well, Bill Lawry - resonates with spectators big time, Ravi Sashtri/Mark Nicholas - Fills energy, Sunil Gavaskar - I've not seen a better poker, Harsha - When I am playing scrabble & watching cricket at the same time.
I use mute button on remote for - Arun Lal, Laxman Sivaramakrishnan, Waqar Younis, Ranjith Fernando (I found a mute button on my laptop too!)
BTW - Mandira Bedi, Gautam Bhemani etc do not fall under 'cheerleaders' category.
