A shirtfront of an era

We all know that this is a good age for batting, a shirtfront of an era, as it were. Kunal Ganju, in a piece titled "Batting through the ages", reinforces this belief with a couple of graphical illustrations.

Also see these two pieces on the same subject from Cricinfo's archives: "Bowling's dark age" by Gideon Haigh; and "Is there a crisis in cricket?" from 23 Yards.
