He has only been bowling in t/20 cricket and as a result isn't strong enough to bowl at 90mph at the age of 19. It is about gradually increasing the workload on a young bowler by making him play a few fc games and maybe a test match or two. The more overs he bowls the stronger he will get. Why did he play that stupid CL? I also see that Cooley and co. will look to change his action now and that never helps.
SA have managed Dale Steyn very well. He too made his test debut at a very young age but has played only about 80 onedayers.
http://www.espncricinfo.com/australia-v ... 89248.htmlI again go back to what the great Waqar Younis said about fast bowling,
"Biomechanists probably would disagree with me, but based on my experience, most fast bowlers in the 1980s and '90s never had people telling us to change or modify our actions, and that if we did not do it we would break our backs. Your body is your best judge. It learns over a period of time to adapt. These days Level 3 and 4 coaches put a lot of emphasis on certain specifics due to the numerous video cameras that have come into play. But I have always believed in allowing the bowler to play with his body and understand the best position and action for himself"
Ah, a bowling coach like Younis will help.
