US Natl B team

Two players from my alma mater UAB were named to the US B team. Is this the US natl amateur team under a new name?

Former UAB midfileder Nnamdi Ngwe and senior midfielder Rogerio Oliveira were both named to the US National "B" Team, as announced by United States soccer officials. Both players, who are training in Milwaukee, Wisc., competed at the US Soccer Festival last weekend and were chosen from a pool of players at the Festival.
