As the end was unfolding live, I was disappointed because a historic win seemed a fitting end to Faf's heroics. But now that some time has passed, I think playing for the draw was the responsible thing to do.
As seen in Adelaide, Morkel is decent at surviving against quicks, but the past has shown that Morkel's batting against off spinners is diabolical at the best of times, let alone a one legged Morkel. If Morkel had arrived at the crease, I think Dhoni would have turned to Ashwin, no matter how ineffectual the latter's bowling had been. Dhoni would remember Amla and Morkel trying in vain to save a test against India in 2010, only to have Morkel befuddled by a straight one from Harbhajan.
I don't think Tahir is the worst Number 11, but he's a man who has already had a terrible test. His confidence and self-belief is probably pretty low after seeing the wicket keeper being preferred over him in the bowling duties. As such, tasking Tahir with the duty to survive a high pressure finish is just asking for further heartbreak. If Steyn or Philander, or both, had perished and had left Morkel or Tahir the task of surviving a couple of overs, it would have been brain-dead cricket from Vernon and Dale. Tail end wickets fell in a clump throughout the test -- signifying that the tail end batsmen of both teams have found the pitch tricky to negotiate -- and had Philander or Steyn been dismissed, I would have classified an Indian win as the likely result.
I think Shami's over of bouncers to Steyn was a smart move -- Steyn has a propensity for driving and slogging over long-on, but he hasn't exhibited many shots to the short pitched stuff. In fact, I recall him being dismissed to short pitched bowling a fair number of times. I don't think there's much he could have done with that over given the protection Shami had at third man and sweeper cover. That over brought the equation down to 16 off 12 balls, essentially deciding the fate of the match. Vern and Steyn might have been able to go at 8 r.p.o with the field spread out, but such an aggressive mindset could have equally exposed Tahir and Morkel. It's a bitter pill to swallow, but I think they made the right decision given the match circumstances. As a cricket fan, it is disappointing that the chance to create history was snubbed, but it pales in comparison to how devastating it would have been had SA contrived to lose the test in the final three overs after the efforts of AB and Faf.
What a final day of Test cricket it was though. It's probably one of my favorite Day 5s. It's quite a coincidence how India was 3 wickets away from a win, just as SA was 3 boundaries away from a win. Only when the number of deliveries remaining whittled down to 2 did both teams drop out of the reckoning, that too at the same time. Wonderful script to a test match end.
