Less than a year ago, Alistair Cook was being lambasted for his poor form, both with the bat and his poor captaincy. Yesterday, he joined two of England's greats as only the third England captain of all time to win two home Ashes series - the others being W.G.Grace and Mike Brearley.
England, as a whole, have turned the cricketing world upside down from abject failures a year ago, to stunning Ashes winners now.
What do folk put such turnarounds - both Cook as an individual and the team/squad as a whole - down to?
