If a night watchman substituted the regular batsmen to preserve wickets, it would have definitely helped the Indian side.
If we look at the Eng vs SA test at Edgbaston yesterday, Skipper Smith sent Paul Harris as the night watchman. It was a sensible decision. Even if England has made quite a come back in the Test thanks to some good stuff from Flintoff, England still had to work for the wickets than serving wickets on platter to your opponent.
One down and periliously the last recognised batting pair at the crease India needs to apply itself now, otherwise it will be hard to come back in the second innings, as it seems the new comer in the Sri Lanka team will give a run for the money to the Indians. Dravid nicknamed ' The Wall ' has been breached quite a few times and it doesn't happen to simple deliveries. There is good amount of talent in those wicket taking deliveries and its now or never for the Indians in this series.
