Only in your mind is that the case. Even Umesh took a 10fer in his last test. On a SC pitch just like Abbas. If that is the criteria then Umesh>Abbas.
I have seen enough hype here on PP to not take things seriously.
I have seen dozens of posts of "Babar better than Kohli", "Yasir better than Warne", "Amir better than Wasim" and a plethora of other absurd notions to know that this place is the king of hyping Pak players.
And then when these same players don't perform, the same fans who hype them then go on to tear these players apart.
Both of those behaviours are just as ridiculous and should be avoided as much as possible. But then this place has its own rules.
