What the heck, my two cents...
I have no doubt some teams played with their full rosters and have been the same team since immediately after State Cup, but my opinion is that is probably the exception rather than the rule.
That time of year is infamous for girls playing softball and other sports. You have Strikers who is well respected and uses EGSL as an opportunity to merge both their White & Black teams for EGSL for player evaluation. You also have the kids that honored their commitments to their clubs and were trying out for teams after State Cup before summer rolls around, and like others have pointed out you have families that take into account that this is probably the slowest time of year for soccer and were taking a much needed break.
Outside of the inception of EGSL, the months between State Cup and the Summer Tournaments (Beginning in May) has been regarded by most to be the "preseason" at the youngers. CSL and SCDSL Spring Leagues have never been an attractive draw for teams, and EGSL had to dangle incentives to get clubs and teams to come out and play earlier than usual in an attempt to promote the league.
Having said all that, I concur with
@stork71 in that this was a request to see about expanding on the current data set for the rankings and it started to turn into something else. Thank goodness for
@ajaxahi firing some friendly shots to lighten up the mood!
I think what gets lost is that
@TangoCity was looking for a simple beginning marker to input the data for the rankings. All this conjecture about the validity of EGSL could be a mute point if inputting the data proves to be more problematic for the guy putting in the work to provide this "freebie" to the group.
