Or another idea , instead of coaches , PCB should ensure for Pakistan matches the broadcasters hire commentators out of the likes of Ian Chappel, Mark Taylor, Shane Warne, Nasser Hussain, Michael Holding , Sunil Gavaskar.
Forget your mediocre local coaches , these respected commentators through their analysis on TV replays , will give you all the feedback and coaching tips Pakistani players need. The rest is up to the players to take that feedback on board and apply it , and the best part is if players were serious about improvement they could even privately reach out to these legends on the side and ask for their tips and practical demo.
