if a batsman is great in tests, he should be labled as a test batsman, and should not be given a chance in ODI
1.a. However if a batsman fails in test, he can be given a chance in ODI.
if a selected team fails to perform in a major event like World Cup, call all the losers back in the team. Losers, being the ones who were not selected for the event.
if you want to end a player’s long career, do not give him a playing slot for a long period of time. Then give him a final chance, and regardless of whether he performs or not, discard him forever.
Examples of Rule #1: Asim Kamal. he is branded as test batsman, because he performed better in tests. Unlike Farhat, Hafeez, Yasir etc who were not as good in tests, so were considered for ODI. Had Asim knew this rule, he would not have performed as good in tests and would have saved his career.
Example of Rule #3: Javed Miandad was given a long break until he got the chance to play in 1996 world cup quarter final against India. He scored 38, but the score was irrelevant. Saeed Anwer given a long break and put in the side for 2003 world cup. He scored a hundred followed by a 40 not out. Again what a waste, as he was to be thrown out anyways, courtasy to the devine plan of PCB.
Well, there are other rules as well, if a player has "potential and talent" keep playing him for years even if he shows some performance once in 10-15 games, one example would be Mohammad Sami, Imran Farhat.
Here are the laws of physics as they apply to PCB:
A player sele-acted will remain sel-acted untill and unless an external force is acted upon the sel-action committee. Similarly, a player dropped will remain dropped untill and unless an external force acts upon the SC.
The sel-action or desel-action of a player in both forms of international cricket is directly proportional to the force applied on PCB and the mass of the individual applying the force and takes place in the direction of the force applied (either selected or dropped).
For every sel-action there is an equal and opposite desel-action (dropping) of a player of equal capacity.
The voice of an angry relative of a dropped player travels at the speed of sound as per the surrounding density of air (from hot headed officials)
Talent can neither be created nor destroyed in a player. It can only change its form from mass of the player to performance of the player. ( The reverse also applies)
E = MC2 : Mass of a player is interchangeable with the energy of the player travelling at the speed of light to and from the team while either being dropped or selected.
When a player falls in performance he is travelling directly proportional to the force of gravity and has an acceleration of 9.8 meter per second per second.
When a player is thrown into the waters of unknown batting conditions, the player experiences a force directly proportional to the volume displaced.
The moment given to a player is the force of the PCB acting through the arm of the selection committee. The moment given is directly proportional to force and the length of the arms of the members of the selection committee.
When the batsmen pass through a converging pitch, the pressure on them drops and their velocity to exit the pitch increases. The velocity reaches the mach no. (speed of sound) if the exit pressure and temperature are equal to mach conditions.

Mohammad Sami has potential, talent, both the potential and the talent and much, much, much, much more to offer. PEOPLE!!! 
hahaha this should be in jokes lol
