You play more club games in DA. You play more overall games if you play ECNL and HS. I think most would agree that the HS games don't count (or even detract) from development.Oops.....then that counts toward development that you don’t get in DA (assuming of course you don’t get hurt). So if you add up the real difference in days/spent with your club “developing,” the difference is probably minimal.
There are two fewer days of training in ECNL each week. Some would argue that is unnecessary and leads to burnout. And some ECNL kids spend those two days training independently. But no one would argue that there is a minimal difference in days spent with the club between DA and ECNL.
