You can only lose 'total' faith if you are sure that everything is there for the players to nourish their game and still the system is not able to produce good players. The thing about PCB is that they are just after short term things, change and chop players, change a captain, change a coach, increase or decrease teams in domestic circuit etc.
No one in PCB is willing to improve the pitches used in domestic circuit, the coaching provided at domestic level, the umpiring standard at domestic level.
The club cricket in pakistan is almost non existent, there is no school cricket. If a kid wants to become a cricketer in pakistan, he doesnt know where to start. Only probably the under 19 cricket is something that os functional. I watched some clips from ranji cricket and they have pitched which have bounce and they leave grass on for the seamers help, and then they have pitches that help spinners. What do we have? Dead pitches all over pakistan, remember to create spinning tracks pakistan had to use artificial means against england and west indies. Also PCB being run by the people who dont know anything about cricket.
There is so much room for improvement in the system, instead of just makimg changes in the team staff and members, make changes at grass root levels.
The current team reflects the system we have at place.
