I know this is quite late but your arrogance annoys me...greatly. In fact, so much I registered on a bloody Runescap forum. Soccer is not played with a truncated icosahedron at all, if that was indeed the case then it would not roll and would hurt if kicked on one of its edges (something a sphere does not possess). A football is a sphere, however, it is commonly designed as a spherical polyhedron which is why they tend to have funky-looking patterns on them. So if a football is a spherical polyhedron and a spherical polyhedron is spherical (as the name suggests) then something that is spherical can be called a ball. Thus, justifying football being called football.
