Simple, 8 ECNL teams v. 13 DA teams, meaning the talent was even more concentrated last year. Don’t get me wrong DA is the top league for a good portion of the age groups and has the biggest chunk of the talent, but ECNL had more.
Do you mean 11 ECNL teams from last year v. 13 DA teams this year? It was also 12 ECNL teams a few years back before LVPSA was dropped.
