Smith/Williamson/Root
Fab 5.
In your usual manner you are trying to overrate Virat Kohli and put the daylight at the wrong place.
In the test format there is just one daylight it's between Steven Smith and the rest.
As I often say, stats are not enough to prove the dominance of Steven Smith and they don't necessarily show how dominating he has been. But here I will show some stats just for everyone to see where the daylight is.
Overall average :
Smith : 62, 84
Kohli: 53,62
Root : 48,40
Williamson : 51,35
We can clearly see where is the daylight. A difference of 9 between Smith and Kohli. Where has a difference of 2.3 between Kohli and Williamson.
Away average :
Smith : 60.15
Kohli: 44.36
Root : 44.27
Williamson : 42.53
Smith's away average is about 16 more than the rest of the fab 4. The three others are in the same bracket. So again we can see where the daylight is.
Average in Result matches (excluding draw):
Smith : 57.72
Kohli: 50.83
Root : 46.08
Williamson : 47.89
Again the daylight is at the same line. The rest form a little group.
Average in won matches :
Smith : 81
Kohli: 60.50
Root : 61.23
Williamson : 74.35
In this stats, Williamson is better than the other two but Smith is again at the top by a margin.
Number of innings per hundred:
Smith : 5.04
Kohli: 5.37
Root : 9.94
Williamson : 6.62
That is one stat where Kohli is pretty near to Smith and Root is really poor.
Consistency :Innings per score over fifty :
Smith : 2.38
Kohli: 2.96
Root : 2.25
Williamson : 2.62
Although Root is the least consistent in putting big scores he is the most consistent of them all in putting scores over 50.
As I said many times, Root gets the most difficult conditions at home batting at 3 so it's not always easy to score a hundred. Kohli's consistency is the worst of all 4.
There are many more ways to look at all this but one thing is pretty sure for the moment being :
Smith is in his league of his own as a test player. For this to change it will need 3/4 years of consistent failure by Smith and great batting by one of the 3. And that isn't happening...
Smith
Daylight
Kohli, Root, Williamson.
Then you can compare the other 3 to see who is better between them. For me, at the moment Williamson is behind because of too much minnow bashing. Kohli and Root it's pretty close. Both average under 40 in three countries each and have many things to rectify.
