The 1990s US expansion featured teams with all-American rosters. My understanding is that the ratio didn’t jive with US labour law.
If US teams were ever added again, (perhaps judiciously in mid sized northern US markets without major NFL or NCAA programs) could the CFL perhaps impose a regional ratio instead to promote parity with the Canadian teams?
That is that US clubs would have a portion of their roster (equal in size to that of the “national player” contingent of Canadian clubs) drawn exclusively from a regional catchment area. This catchment area would perhaps be based on population rather than a strict physical geographic radius.
Anyone have insights whether this would be legal in the US? if it were kosher, it would probably only be fair if the CFL stuck to northern states. The calibre and quantity of players in the south would provide an unfair advantage to southern based teams.
