I would still say, give Ishant Sharma a "break", let him sort out the technical issues with his bowling. M not one of those who has criticized him, but he's just 25, he has time on his side, maybe working with a good bowling coach might help him. At the start of his career, he bowled these big inswingers from short of the good length with extra bounce, it created a lot of problems for the batsmen. Currently, he bowls a couple of outstanding spells in a match, but the rest of the time, he's just ineffective. Ishant has already got a lot of experience, his fitness level is high, gets extra bounce with his height, if he can get a bit more consistent, India will have a reliable test bowler for the next few years.
