My theory is Ajmals's action will be forgotten if England win the series just as this recent report from Cricinfo:
"The growing quality of pitches in the UAE has contributed to two engrossing Tests. It was widely anticipated that this could be a tedious series on unresponsive pitches. Instead, there has been enough life for bowlers to relish an even contest."
after every one condemning these pitches initially. Or this from the same match report
"But the main benefits have come from the advent of DRS. Technology is rapidly making defensive pad play a thing of the past as umpires grant lbw decisions where once they would have looked askance. The game is different now: livelier, more combative and eminently more watchable. The downside is that lbw decisions are at an all-time high but with the future of Test cricket in such doubt, technology has provided a timely shot in the arm. "
which is certainly more upbeat about the impact of DRS than Bob Willis after Ajmal's five lbws in the first innings of the first test.
Of course this is all conjecture...
