Two sets of issues "doomed" the NOC - which led to SL expansion, formation of the current GCC, and formation of the current WRC
The first issue was the top division for football, who would be in it
The second issue was some of the travel involved as the divisions were more competitively driven than geographically driven across sports
The present SL does not have travel issues to the extent that the NOC did. Wadsworth would be the geographic outlier in the bigger division, but their alternatives are limited. Adding Wooster or Louisville via an expansion wold create travel issues. Adding Solon would not have - except for Wadsworth - though the addition of Solon evidently was not favored by at least three teams.
