Looking at the assignments, it seems that the Georgetown men (#17 nationally) may be the star of the men's gold race as the only other "full" team that is receiving votes in the field would be Navy (receiving votes). I think Columbia men (#28) will be sending their B-squad as they are in the brown race.
The women's gold race should be more exciting as Villanova (#15), Utah State (#21), and Miss State (#24) are entered. The brown race will feature Georgetown (#23) and Columbia (RV) but I think they will be the B-squads.
