Established Evidence
Ponting’s case rests on a clear split in Labuschagne’s scoring. Before the 2023 Ashes, he scored almost equally well off the front foot and back foot; since then, his back-foot returns have collapsed far more sharply, which suggests bowlers have found a length that blunts his scoring options. The dismissal in Mackay may have owed something to luck, but the longer slump looks statistical as well as technical.
Counterpoints
Ponting accepts that the Mackay wicket itself was more down to luck than a single technical mistake, so one dismissal does not by itself prove the problem.
The numbers cited come from Cricviz and show a sharp recent decline, but they still describe a specific stretch of Labuschagne’s Test career rather than a final verdict on what comes next.
