The choking allegations are going to belittle quality of our performance here, getting 2 wickets in the first 2 overs caused the nerves that have led to this, the Jimmy one in particular is perfect swing bowling and deserves credit for the quality bowling rather than any perceived nerves from SA.
As for Warne, I think he's a great commentator, like David Lloyd, Ian Botham and Michael Holding, he's very interesting and has loads of good anecdotes, on top of an excellent understanding of all aspects of the game. More than any other sport cricket allows for the commentators to bring their personality to things and, to give sky credit, the team of commentators as a group is excellent, with the 4 named marginally ahead of the rest, because they've got big personalities.
