The trouble is that legends such as Wasim/Waqar don't think in the English language, and Rambo can. Unfortunately his thoughts are a leaky pail of julabain. Bazid is reasonably fluent in English but talks like a corpse with few thoughts worth sharing.
Pakistani cricketers, both former and current, are rarely educated and are not equipped to offer analysis in what is to them a foreign language.
They may have been quick to react on the field and were great at outfoxing opposition players, but verbal language is where they're not quick and can offer little insight.
Even Imran Khan as a commentator was awful. Probably because he didn't commentate enough, but he rarely offered any analysis and just read the pictures we were seeing.
The issue is that cricket media is a mafia of ex-players and too many of them are not what the games needs to make listening pleasurable.
On female commentators: Isa isn't great but she isn't terrible. I'd listen to her over any Pakistani commentator, Shastri [he'll be back], BANG/NZ commentators [except Ed Smith] etc.
