Ah come on Jeet... You can't seriously even mention A. Nehra and Irfan in the same sentence and be serious..
Nehra's emergence?? He's still a mediocre bowler and a horrible horrible fielder/batsman...
If at worse you can say Irfan is a mediocre bowler, an athletic fielder, and a good batsman..
So how does being equal in 1 aspect of the game and being clearly much better in the other 2 be even close??
If I was selector I wouldn't play any other spinners besides Bhajji and even that on just spinner friendly pitch.. The reason for that we have so many part time bowlers.. Yuvi, Shewag, Sachin, Raina, Sharma, Yusfu etc... So play just 3 bowlers Ishant/P. Kumar (I would say P. Kumar lately), Zaheer and Bhajji and that leaves you 20 overs to be filled with bowlers such as Irfan and all the other part time bowlers I mentioned..
Is it really that complicated?? I mean with that decent bowling attack, imagine our batting line up... Ahh I'm getting all happy and excited about a line up that would be amazing but will never happen due to Indian cricket politics..
