According to Dick's, American football shoulder pads are about $150-$300, cups are $15-$25 or $50 if your FTB, pants are $50-$80, hip and tail pads $15-$25 (does anyone wear these anymore, neon deon sanders look?), knee pads about $15, ultra cool neck rolls about $50-$70, helmets $80-$170, footballs $10-$90 depending on what you need, field goal post $7,400.
Soccer ball, $50-$150. New world cup ball, kind of ugly but I get it. You can play soccer with the toy ball I bought at the grocery store, $4.99.
But I think I'm figuring out why its popular around the world.
