I can see that since BMS is the 3rd largest sports venue in the country and 7th largest in the world.Not really an apples to apples comparison now is it, given that KC--and the Kansas City Chiefs--are a wee bit more famous than Bristol and the Bristol Motor Redneckway.
BMS has a capacity of 162,000+ and had 156,900 at the most attended football game ever, which is almost exactly double of the 78,097 capacity of Arrowhead Stadium.
