ECNL and MLS (and GA for that matter) are basically recruiting the whole year (if not they are not doing their job). They should already know who they want when it comes to tryout time. However ASA and SSA are at (basically) the same level with (basically) the same recruiting rules. If I am a club in one of those leagues (ASA or SSA), I would want my league to have the earliest tryout dates possible. There is an advantage to going first. However, from what I see for the club's tryouts dates, they are all the first week in May. This doesn't make sense from a business perspective. I'd prefer for my player to go to as many tryouts as possible and see what all the options are. But clubs are gonna do what clubs are gonna do....
