I think you're just trying to set up a non-sequitur of an argument so that you can pretend any future success can be attributed to the idiot who gave us 2 drastically bleak years.
In 2 years he managed to take our NYC team from last all the way to second last. If there was a focus on youth, it wasn't a very good one. And yes, you'll pretend that he was focussing on younger youth - but that doesn't follow either. There's no reason we couldn't have a youth policy which actually saw our NYC improve from last to mediocre.
The unfortunate fact is that the youth movement had 2 years and didn't move anywhere. So IF a youth movement is to succeed it will due to what happens from now onwards. That is, we need to get one started and get it going. Just having the idea isn't anything new, the failure to implement it lead to the sacking, of that there's little doubt.
