I think there are many other players who need much more serious attention before Pathan. Irfhan was sent because of bad form in bowling, but lets not forget he was in supreme form in batting when rest of the batsman failed.
Sehwag is a specialist batsman and has shown no signs to stay on the stumps which is required in a test match.
Also, just see the team of 11, after excluding Pathan, just one left-hand batsman(Ganguly) out of 11. That needs attention as well.
