I have been saying this since 2007 to be perfectly honest. I predicted Ponting to have no hope of coming close to Sachin's test runs record, and on top of that, that Kallis would overtake Ponting and be a real threat to Sachin.
The main reason was I believed Sachin and Kallis had the techniques behind them to handle old age, whereas Ponting's reflexes and eyes waning would have a bigger impact on his game.
However even though what I predicted ended up coming true, there are flaws in my argument. Why is Dravid then suffering, since his technique has always been very good? He's not an eye player like Ponting. The other flaw in my argument is why the hell did Lara get better the older he got? He most definitely was a player who relied on his reflexes, especially compared to Dravid.
Had Lara waned as he got older, and Dravid had a similar path to Kallis, my theory would be perfect. But Dravid and Lara make no sense
