You're not the only one wondering, I've been through it myself. When my younger brother started playing cricket, we came across the fact that the academy already has video analysis and different digital panels that immediately give out statistics on the game. You can see how often he hits the ball, how he moves, where he fails. And it really helps not only the coaches, but also the guys themselves. I recently read an article that describes all of this. You can see it here: https://possible11.com/blog/crickets-talent-factory-how-the-ipl-finds-and-develops-stars/. It explains how IPL uses analytics and technology to find promising players. It's no longer just the coach's intuition working, but real data that can't just be ignored. So it's definitely not just a fashion, but already part of the system.
