The official name of the building is
Louis Brown Athletic Center (RAC)
It hasn't as far as I know. There's still a little Louis Brown plaque in there.
The facilities pages on the Rutgers.edu website (as well as the physical master plan approved a few months ago) refer to the building as Louis Brown Athletic Center (RAC).
Yeah that's what I thought.I asked around today.
It's officially the Rutgers Athletic Center, again.
Even on the tickets is printed "RAC"
