Yusuf Pathan won the Duleep Trophy with a double century. Nobody noticed. Yusuf Pathan scored a 150 and took ten wickets in a match. Nobody noticed. Yusuf Pathan's century in an ODI changed that ODI and India won. Once more. Still, twice over, nobody noticed. Ashwin has a Test average of 42 with the bat. Nobody seems to notice.
While Jadeja's two triple centuries are a significant achievement, that doesn't suggest he can win matches for India, or even make a difference in the Indian side. Rather, you now know how cheap runs can get in that area. Instead, we need to encourage the likes of Pankaj Singh, Parvinder Awana, Sandeep Sharma, Bhuv Kumar and Rishi Dhawan, who are getting plenty of wickets, and can make a difference in the national side.
Express pacers make a difference. All-rounders who are strike bowlers make a difference. Batsmen scoring runs in difficult conditions (Delhi, Ghaziabad, Lahli) make a difference. Not two triple centuries in Gujarat and little outside of that- at least JJ Singh, Paras Dogra and Yashpal Singh get runs regularly.
