On the topic of Johnson, since the start of the Ashes series he has bowled in 15 innings, taken 37 wickets at an average of 30.48 with an economy of 4.18 and a strike rate of 44.1!
While the economy is worrying, his strike rate is mind blowing, 8.9 less than his career strike rate! And the rest of his stats are all pretty good.
If that's him in a form lapse.... Although tbh, they may have been boosted by performances in Adelaide and Headingley, and he has taken a lot of tail end wickets.....
But still, pretty decent stats....
