same size as Grand Rapids, Michigan and Harrisburg, Pennsylvania.
Consider Orlando and Sacramento are about twice as large and only have NBA teams. Markets that have at least 250,000 more "TV homes" than Vegas and don't have an NBA team: Tampa (but Orlando is 90 minutes away), Seattle, St. Louis, Pittsburgh, Baltimore (90 minutes to both DC and Philly), Raleigh, Nashville, and San Diego (less than 90 minutes to LA).
Vegas is still larger than New Orleans and Memphis by a substantial amount, and slightly larger than OKC.
