Not only spinners, overall quality isn't there to be honest. Apart from Babar, I doubt how many ........
Outside Babar, Imad is decent in Asia while Amir can create some moments with new ball - that's it. Add to that horrible fitness, poor running, lethargic fielding - costing may be 10-12 extra runs at least than par, which is massive in a 20 over game. I read PAK fans to bring IND of 90s & Tendulkar here, in reference to Babar's pain ......guys, that IND team in 1990s also had Azhar, Kumble, Srinath, Dravid, Ganguly, Jadeja as well - don't insult respected people in your desperation - it'll bite you back.
The gap with AUS is massive - today, it looked close on scorecard (I didn't see the game), because Aussies were always in cruise control; won with like 10 balls and 7 wickets at hand, which is a good gap in T20I. Apparently, it looks like Smith played a blinder to win it, but not every day Warner & Finch will be back inside 50, and Maxi will come back .... on top of that Aussies can bring Tye or Stanlake for that loose 3rd pacer's spot. It won't be even a contest the day just about 2-3 Aussies fire together, gap is that wide.
Some hard calls need to be taken but Management is stuck in between - they are trying to protect that fake No. 1 ranking (PAK shouldn't be ahead of AUS, ENG, IND, NZ, SAF definitely and probably WIN as well), therefore reluctant to start from scratch, and the new management is desperate to show some results after the SRL series, hence they have gone back to players without any future (& honestly, these obsolete players are delivering somewhat - today 2 of the 3 best players were Iftekhar & Irfaaaan), but it's just complicating the problem.
To be honest, I was expecting a better show from PAK than the SRL team that toured AUS recently - don't think it's the case; Aussies would have won the first game at equal opposite of SRL's first game (by 10/9 wickets and inside 67-75% overs, and they were without Maxi, who slaughtered Lankans in 1st game). Next two years, teams will prepare for two WCs - so no free lunch and if every team plays their best T20 XI against PAK, within a year that shiny ranking will melt faster than spring snow.
It'll be a slow, painful & tough way to recovery, if it happens (didn't happen in Hockey though) - PAK fans should keep patience.
