It's good to see a frontline pace bowler leading the team. But PZ's problem this year is they don't the 20-over bowling they have had before. Wahab is holding up okay. But Hasan Ali has been mostly out of sorts. As a bowling unit they're going for too many runs than they did before.
In previous years, Peshawar's pace battery used to be formidable and barely had a weak line. They had Wahab, Hasan Ali (in-form), Chris Jordan, Tymal Mills and Pollard or Dawson pitching in.
Wahab might be a good leader, but he can't do much with what he has at the moment. The likes of Rahat Ali and Yasir Shah don't threaten most opposition batsmen. They might claw through to the playoffs, but if they're going to lose whenever they bat first, it's not really going to get them to the final.
