For example, if some player feels neglected by their State board then S/he can move and play for another state, given they have the quality. Even if they don't make it into the international setup, they can make their career in the IPL and if they are not cut out for IPL as well then there is domestic cricket. In all this circlejerk, if you are talented you'll get a chance for sure.
This proves If you are talented enough, you have many opportunities where you can try yourself. But if you talk about my country, there are no state boards. Only one BCB and private clubs. Most of the Bangladeshi young players does not get enough chance because of corruption. At the same time, some players with zero talent get endless chance because some specific person likes them.
Also, IMO successful campaign in u-19 WC is no magic wand for a successful international career. You have to perform consistently with the right attitude.
True. But what if you still performing and see no one even paying attention to you. This Bijoy guy was the highest run gater in the last season and the 2nd highest run gater in the previous season. Yet, BCB doesn't consider him.
