Amir has improved and will improve further with right diet, training and help from Wasim. He may not become mindblowing Amir of 2010 English tour but Insha'Allah He will become Excellent Test pacer.
He deserved to be dropped for this series based on merit but he was picked and did not disappoint and was much improved. He had a very good series.
We have no express pacer in domestic. Not even one.
We have 2 young FC Right Arm pacers who are currently Fast Medium ie Bilal Shah Adridi & Atif Jabbar. Both at best can become Right Arm Fast provided they put in hard yards. They both can outdo Wahab in Test Cricket.
Than we have guys like Adeel Khan, Ehtisham Sultan, Mohammad Zahid junior & Mohammad Umar aka Umari Pacer who are all capable of bowling few deliveries in FAST range and if developed well they can become good pacers. None has made FC debut Yet.
We don’t have any Wasim, Waqar, Shoaib, Imran in domestic. No express pacer or future express pacer but we have a decent pool.
Majority of James, Anderson, Philander, McGrath's Test Wickets have been on deliveries which had same medium fast speed of Abass. Only McGrath was 4 & Asif was 2 inches taller than Abass which gives them edge.
Abass has looked better than Tanveer Ahmed, Ehsan, Rahat, Junaid, Sohail, Aizaz, Imran jnr, Gul etc and that's all what matters. If He can sustain his performances and improve his endurance stamenna than He is exactly what we need.
The question you, and those like you, need to ask is why Pakistan aren't producing the express pacers any longer. In fact, they haven't produced anyone since Sami and Riaz, both of whom were around before 2003, coincidentally when Bob Woolmer took over, but it is no coincidence in my opinion, Woolmer's laptop revolution and the preponderance of clueless domestic coaches with worse-than-useless ICC accreditations is probably the cause. Genuine fast bowlers are largely born, not made, and the obsession with diet, training, messing about with actions by coaches with a one-size-fits-all approach is the problem.
I'd be in favour of a think tank, much like Miandad suggested, of former players, Wasim, Waqar, Shoaib and even Sarfraz to take the best and make them better. You can run on the treadmill for as long as you like, eat as many protein shakes as you like whilst tinkering with their actions, you'll still produce an inferior result and the last 15 years is ample proof of that. All your great fast bowlers would never have bowled fast had they been subjected to what is being done to the current crop. Predictably, Amir is heading for 130K trundledome.
From 1993-2003 you had Wasim, Waqar, Zahid, Akhtar, Mo Akram, Nadeem Iqbal, a guy called Mohammed Ali, even Rana Naved was apparently express when younger, Sami, Riaz, even Yasir Arafat could go past 90mph at times and one Mo Irshad who was apparently ruined by action changing according to comments I've read here. I'm sure there were others too.
Much like Usain Bolt was, I've been a fan of the Pakistan of yesteryear, it's time to wake up and take stock.
