I read this on the DNA (a mumbai newspaper) website. Clearly, all these talented young players moved to ICL cause they did not get opportunity from BCCI. It is an interview of Inzamam-ul-Haq who is leading Hyderabad heroes in the ICL. You can read the entire interview on the DNA website:
Q: How has the experience been so far?
Inzamam: It has been quite enriching. The talent these youngsters have is amazing. I am leading the Hyderabad Heroes and some of its players are good enough to get into any national side. I am particularly impressed by Ambati Rayudu and Anirudh Singh and am sure they have much more to give to Indian cricket.
