Not RPI specifically, but the days of us hosting just because of the large crowds are long gone (like a lot of the crowds). There won't be more than a couple of #1 seeds that don't host, and even then the host will usually be a team from a mid-major conference and a high #2 seed. Also, with LSU, UF, USC & Kentucky almost locks to host, they're not about to give a 5th regional to a #2 seed.
