on one hand it's worth noting that mcgrath has been helping with their pace academy for a while now and india still haven't produced any good pacers.
on the other it's also worth noting that a number have come in to the team quite good before turning to dross.
He has replaced Denis Lille in the MRF pace academy for a while now as you said but I don't think he has worked with any of our current fast bowling group. Our current group of young bowlers which includes B.Kumar, Varun Aaron, Umesh Yadav, and Shami. If he can work with them before the world cup than it will be great because all of them have potential and are very young but if they can get that accuracy, it will be great. But than again it comes back to the question I asked in my last post. What is Joe Dawes going to do?
