These jobs comes from your passion, don't think your playing career has anything to do with it. Arlott or Cardas hardly played cricket, neither Pelham Warner or PAK's own Omar Quarishi. You need to follow the game, know players and link dots while commenting with facts and past examples, so that viewers can make a story out of the situation - otherwise anyone good in English can describe what is happening in middle like a robot.
I don't think these days people are interested to listen "beaten by out swinger", "cut to deep point for 1", because they can see it. When I used to hear ABC cricket commentary, it was like visualizing a thriller over radio when Benaud, Lawry, Tony or IC used to elaborate a "situation" - it stressed the imagination of audience. The best thing they could do is, describe a situation and forecast something that happen or a tactical analysis of any event, from which you can draw a conclusion. If you ever had listened a pitch report by Benaud, Jeremy Coney or Tony, you probably can see the difference on usual rant these days (in fact not rant - now they finishes in in 2 lines). Gavaskar was Star Sport's anchor for 1992 WC, and I can proudly say - I learned, lot, lot about the game from that one month - how the skills of the game can be described through a tactical landscape.
Rameez's (or any PAK commi) problem is they sound absolute clueless when taking about anything else than what we are watching in tv. I know, he gets over excited and his English doesn't help him much, but the amount of knowledge Ather Ali possess about BD cricket and cricketers, one has to be surprised; while Shamim Choudhury (probably lives in between Dhaka - Toronto now), spends lots of time reading cricket books - these things help as commentator than what you did as cricketer or achieved as a team member.
Rameez is actually better, probably best among recent PAK commis, because at least he can speak fluent English, and can manage his stumbles

. WY is perfectly matching his Captaincy & Coaching days with mouthpiece at hand.
