Rahat is from Multan and is also Punjabi. Asif was called "A 400 test wicket bowler" by Michael Holding. McGrath rarely reached 140 after the first few years of his career. In the series against India in 2006 Asif bowled up to 145kph. He slowed down later but in England in 2010 I clearly remember him getting 87mph. 100 wickets in 20 tests is nothing to be laughed at. You are sounding like a total idiot right now.
Rahat is good though, I didn't rate him at first and preferred Ehsan, but at 26 Rahat is mature and has a few tests under him now. He is now improving under Waqar Younis. I would try out Ehsan and Rahat in the odis against NZ, one of them should go to the World Cup. I don't really like Wahab Riaz, he is our quickest bowler but is usually all over the place. Rahat has more control, and can bowl 140kph as well, on these dead flat tracks. He needs to become more aggressive and focused. I think Rahat has a great future if he continues improving, if he does, he will likely end up with more wickets than Asif, but don' t for a second say that Asif was overrated or a one trick pony. He was a genuine magician.
