>>[Coach P] So, by this logic, should SC teams be in the R3PL? So far this season SC teams have only won 30% of their R3PL matches.<<
There is quite a bit of discussion concerning the depth of SC soccer and the extent of participation in RIIIPL-East by SC teams by RIIIPL-East folks. Here's the short answer from the perspective of the statistics: typically in the last few years, the first-seeded SC team has been competitive in RIIIPL-East and the second-seeded SC team has been grossly non-competitive with amazingly high goal differentials.
There are exceptions to this -- for example, last year in the U15B bracket two SC teams (DSC and CESA) were among the highest ranked RIIIPL-East teams. However, this has been the exception rather than the rule -- and part of the reason you see more GA, NC, etc. teams in RIIIPL-East than SC teams.
Hopefully, as Bridge has shown and as CUFC is attempting to show, SC can be more competitive in RIIIPL-East with both its first- and second-seeded teams. Please note, however, that SC isn't getting more competitive in RIIIPL-East by playing tougher competition -- it is getting more competitive largely through structural change occurring through the creation of "merged" or "allied" clubs such as CUFC and Bridge.
