At one point or another good players will play in various leagues for various programs various coaches, high schools...at the end no one really cares. Even some of the local stars (Eichel, Donato, Hannifin...) that have moved on have numerous teams they played for like private teams, tournament teams, EHF teams, BA teams, National team, Junior teams prep teams, high school teams so to hang it all on the EHF is really silly unless your kid is < 12 then you have no idea what you are in for but you will quickly learn.

EHF is a good place to play but it's not the only place.
