It's not explicitly stated which team.Men's team or women's team? As for the men's team, are there any name theories? "There may be a person named X".
If it's the men's team and the mother/father were both white, then it's either Dwight or Jake. Otherwise Jazz, Dex, and Larry are also contenders. Of course, we haven't met the female first team yet and we don't know if there's more male players we haven't seen.
We don't know Dwight's relationship to Sasha - could he be her brother (i.e. a Petrova) or a Revera?
