In fact, I do not understand what you mean by saying
Pakistan managed to win the trophy only twice out of 14 attempts.
Pakistan has participated in the Asia Cup competition for a total of 15 times (including the recently completed one), and out of this they managed to win the trophy only 2 times. India has won 7 times (50% strike rate) and Sri Lanka is close behind. So there is something wrong with the way the Pakistan team is performing. On one match they are defeating the top ranking team (India) and in the next match they are struggling against a tier-2 test nation. Absence of Shaheen is just an excuse. If that is the case, then India was also missing their strike bowlers.
No, I understand what you wanted to say, but I don't understand what you are trying to implement by saying that.
A team taking part in a certain tournament for a long time does not mean that they are going to be good in it. They have taken part in the Asia cup for 15 times but we also have to remember that Asia is the region that has the most competitive cricket teams in the world.
India has always been one of the best teams in the Asian region for a long time. Not only in the Asian region back also in the whole world, India has been one of the best.
So, if you are trying to say that Pakistan has played 15 times in the Asia Cup and only has two Asia cup wins and you are trying to implement that they should have won more than that I am not going to agree.
