Think there is a big reason for this, the knowledge of bio mechanics among youngsters and coaches, also sports is much more attractive and with IPL rewards. Earlier few people took up fast bowling unless they had required physical traits per old school of thought.
India is under utilizing its talent and had been for quite a long time, smaller centers and teams are now more visible and players getting more exposure helps a lot. For me Umran Malik Kuldeep Sen is a must looking at the future, every team needs enforcers, who can scare with pace and run through line ups, skill bowlers who can bowl like Shami and Steyn.
Nagarkoti and Mavi hopefully are not wasted like Varun Aaron and Sudeep Tyagi.
Mohsin, Dayal, Khalil if he has made mental adjustments, Umran, Kuldeep Sen, Mavi should be in our selectors radar for grooming to replace existing bowlers.
