100% true. I would not count Perry, Warren, Portage, Chesterton, Brownsburg, Avon, Mater Dei, etc. among the part-time coaches. You see their coaches at all the ISWA and Youth events all year round.
Sadly, however, these guys are more the exception than the norm. And it is no surprise that they are the ones who have the successful programs. That's the point I'm trying to make. For kids who aren't fortunate enough to have a coach who puts in this level of time and effort year round, their Academy coach probably has spent more time with them and knows them better. The above schools and a handful of others would be the exception.
