Honestly, Jadeja is even more a waste of space than you can imagine. He's no bowling all-rounder- he has taken a single, solitary wicket in five games, and his economy has been higher than that of some pacers. The captain had to take him out of an entire innings just because there were too many left-handers in a batting side- one more piece of evidence that Jadeja needs a lot of protection. Some bowling all-rounder he is. No wonder India struggle to bowl teams out in fifty overs. They're better off playing a proper spinner who takes wickets (if Mishra wasn't handled so horribly, he would fit the bill) and make the bowling competitive.
If this waste of space is carried on purely to make use of his batting, he's actually worse than Sharma and Raina, whom you want to throw out. He's not even up to the all-rounder mark- rather, this is the minimum you'd expect from a frontline bowler, and an element for selecting your top bowlers. We've seen Ashwin shy away from the all-rounder tag, and why not, since we'd like five Ashwins in the bottom five instead of this Jadeja and four non-batsmen. Ashwin is a better option. Irfan is a better option. Praveen is a better option. Either of Mishra or Vinay is a slightly better option. Fit in Zaheer or Ishant or Umesh and you have a strong attack.
India still don't try to take ten wickets, which seems very unlikely with this bowling combination. While rotating the openers is a decent if questionable idea, there's room for rotation of all-rounders. Jadeja is a very poor choice being a poor bowler, and we'd like to have blokes who are bowlers first and foremost- fair, it takes out Yusuf Pathan, but we'd like their ten wickets down often.
