I know very little about NFL, although I really enjoy watching it, but I find it amazing that outside of the QB individual players can make such a massive difference to the fortunes of a team. With the QB it makes sense, it's clearly a very hard position to play and you need outrageous ability in all sorts of different ways. But when the likes of Hopkins gets injured and your whole offence goes to pot... how is it that a position that is seemingly mostly about being a physical specimen and having great hand eye coordination can see such colossal levels between players such that the backups for Hopkins can't do close to what he does. This applies to loads of positions. Some players are just WAY better at rushing the passer than others, but why? You'd of thought, from an ignorant lay person's perspective, that it's basically all down to physical attributes, but it clearly isn't, because the physical differences between a Hopkins and whoever has replaced him is probably tiny, but the difference in outcome is massive. I guess there are skill elements of being a receiver that I just don't see or understand but even these must be pretty small and in lots of ways, 'in the head', rather than much obvious technical superiority.
