The Toyota Center in Houston will celebrate its 20th Anniversary this fall. It was home to the AHL's Aeros until 2013. It has a very good capacity of 17,800 for hockey.
Houston is the 5th-largest city in the US and the largest without an NHL team.
There have been various reports over the years about Rockets' owner Tilman Fertitta's interest in putting a team in the Toyota Center. There have also been rumours that some other owner has expressed interest in putting an NHL team into an as-yet unbuilt arena in the Houston area. Could Tilman swoop in and relocate the Coyotes to block any potential competition?
