Bit late to suggest this given some of the legends that retired for Sri Lanka since last timw they were here but I wonder how much closer the series would have been if it was the second one of the summer.
I remember sitting at the Oval years ago when they pasted Eng. Murali took 16 wkts but their batsmen set it up beautifully. It was the match that was a shootout between Crawley and Hick for (I think) a spot in that winters Ashes squad.
