In another thread that I started - about captaincy - I have been taken to task for consideration of Shadab Khan.
"He's not a frontline spinner" say some people.
"He's not a Test quality batsman" say the same people.
And they are right. But to me that does not negate his value to the Test team.
Consider the cases of Danish Kaneria and Shahid Afridi.
The two men were exact contemporaries.
Kaneria took 261 wickets in 61 Tests at an average of 34.79.
If you exclude matches against Bangladesh, Kaneria took 227 wickets in 56 Tests at an average of 37.55.
Afridi took 48 wickets in 27 Tests at an average of 35.60.
Afridi never played against Bangladesh.
But Shahid Afridi also scored nearly 2000 runs a an average of 36.51.
My argument is that Shahid Afridi was just as good a bowler as Danish Kaneria but was also an authentic Test batsman when he could be bothered to knuckle down. Against India he hit 3 centuries and 3 fifties in 8 Test matches.
Bob Woolmer commented in 2007 - not long before his death - that he wished he could have just played Afridi as his main spinner outside Asia with four quicks.
Outside Asia it is generally enough to have a Moeen Ali style spinner as your sole spinner - someone who is not really a frontline spinner but who is almost a Test class batsman. Dom Bess has not even bowled a single ball in 2 of the 5 Tests that he has played this English summer.
Outside Asia I am not convinced that I want a Yasir Shah style spinner to average 36 with the ball and 17 with the bat. I would rather have a Moeen Ali figure averaging 29 with the bat and 37 with the ball.
And this is where I see Shadab Khan's role for Pakistan.
He is an all-rounder who is a strong second spinner but is not a frontline spinner.
Outside Asia, that's probably more useful than being a frontline spinner who can bat a little.
And in Asia, if the conditions are spin-friendly, then play one or two finger spinners as well. Ashwin and Jadeja are both finger-spinners who can bat, and Sajid Khan and Zafar Gohar could play their roles at numbers 8 or 9 anyway.
The greatest England captain of my lifetime was Ray Illingworth. When I was just a toddler he took England to Australia in 1970-71 and won The Ashes convincingly.
But Illingworth was exactly what Shadab Khan is. An all-rounder who was a second spinner but who had a fighting character and was a leader.
In 61 Tests, Illingworth averaged 23.24 with the bat and took just 122 wickets, at an average of 31.20.
But if you look back at the 1970-71 Ashes, and most of Illy's Test career, you see the same pattern.
Like Pakistan with Mohammad Rizwan, England had a keeper in Alan Knott who could bat at 6. And playing Illy at 7 left open the option of playing 4 quicks - which they did in SENA - or having an extra spinner in Asia.
That's where Shadab Khan has his role for Pakistan. Batting below Rizwan, at Number 7.
In SENA he is probably the sole spinner required, because he allows 4 quicks to play. And in Asia his job as a spin bowler would be to support Zafar Gohar or Sajid Khan and the quicks.
I do not accept that an all-rounder has to be as good as a specialist in batting or bowling.
If a spin-bowling all-rounder at Number 7 can do the following, what's the problem?
50 runs per Test at an average of 33.33
2.4 wickets per Test at an average of 36.64.
Those are Shadab's actual career Test statistics - at the age of 21.
As a batsman, those figures are better than Azhar Ali and Asad Shafiq in the same 6 Test matches.
And as a bowler his average of 36.64 outside Asia is barely different to Yasir Shah's 35.80.
All that matters with an all-rounder is the sum of the parts. It's absurd to compare them to a batting or bowling specialist.
