[MENTION=79064]MMHS[/MENTION] what is the chance of the above joining senior team in 2-3 years
Not sure to be honest - it's not about how good you are, rather there has to be an spot open. Shaw might get a call in Test side, because opening slot is loose, but Gill is a middle order and behind Iyer, but he'll be in squad for sure. 6/7 years back, there was another fantastic kid (Manpreet I believe, 2010 WC), still couldn't make the team & his time is gone I guess. On contrary, Dhawan & Pujara were top scorers of 2004 & 2006 - it took Dhawan long, long time because of Sehwag, Gambhir, T'kar, but Pujara & Rohit made the team quickly. Three pacers, I am not sure actually they are better than what already is there. Remeber, IK Pathan was a sensation at U19 level, so was Ishant and they were physically much gifted than all 3 here. Normally, I have seen Indian pacers starts with a bang, then couple of years time decides to prolong career rather than going for pace. Not sure any of them will have long career for IND though - Agarkar was similar to Nagarkoti, but he could bat and had lot less competition. I think, 2 batsmen has the best chance here.
For Musa, it's almost about luck - whose who, so can't tell. Besides, kid looks much older than his official age, hence what we are watching might be his peak speed - if so, he won't go much further. Jamshed Ahmed was more skilled than any pacer on display today and he was 6'3"+, bowling at least 135K - couldn't find even a FC career after winning U19 WC.
