Coaches have a finite amount of training time with the players, especially on the park. When that's the case, every minute you spend on one thing is a trade-off against something else. What this says to me is that we decided that we were spending too long on something else and not long enough on skills. I'm not sure what we've given up - fitness, game simulations, decision-making, tactics, line-unit sessions etc - but something will receive less time.
It seems like a good idea to me, but I can't say I understand the animosity it has caused. It sounds to me like Lyon is being flexible and open to new ideas, and that the assistant coaches are actually contributing. Given the time spent by people arguing the opposite of that for years, I don't understand why this isn't taken as cause for optimism.
It's almost as if some people are never happy.
