India would do extremely better if they appoint Heath Streak as a bowling coach of India.
He is currently the bowling coach of Bangladesh and he is solely responsible for the improving the quality of Bangladesh bowling attack which in turn was responsible for their success at international level over the last two years.
Mustafizur Rahman, Taskin Ahmed and other successful bowlers are trained under Heath Streak and their success is evident.
If India want to dominate the world of cricket then Bowling is the one department where they have been lacking consistently.
Nehra & Bumrah are short term solutions. But in longer terms we will have to nurture out & out QUALITY FAST BOWLERS who will bowl with SPEED & BRAIN and not brainlessly like Umesh Yadav.
