I have zero knowledge of either of these teams and their rosters. But I wouldn't read too much into it.
Their Discovery team forfeited National Cup. This team didn't have a great record in season, but were in a lot of very close games. Several 1 goal losses and 5 ties.
Their Europa South team played National Cup. They finished in 2nd place in Europa.
Maybe the Discovery team was going to be missing a lot of players (Spring Break, etc). So that team dropped out. But there were some girls that were around to play. So they combined those girls with the other team for National Cup.
They are billing this tryout as a "Champions" bracket team. Are they combining the teams?
