That’s not necessarily the fault of any department or person. Kansas City is a smaller market centered in the heartland, and these states are called “flyover” for a reason. Compared to the bright lights of New York, the over-abundance of attention paid to the entire East Coast or the market size of Los Angeles, it’s impossible to compare apples to oranges.
It also hurts the Chiefs that the on-field product hasn’t historically been great. A single Super Bowl from decades ago won’t exactly compel fans outside of the region to buy jerseys or root for the team. Meanwhile, the Dallas Cowboys remain “America’s Team” due to their many Super Bowl wins and Jerry Jones’s marketing acumen.
