I googled Sport and there is a long definition with a few "sometimes" and "usuallys", leaving it somewhat up to how you wish to define or interpret it. Your opinion that we should stick to the accepted dictionary definition is valid, because the OP asked for our opinions. In my opinion football is definitely something that fits pretty much all of the dictionary's broad definition. I disagree with several posts and agree with others, thus my opinion.
I do not recall quoting you until now I do not think. I am just going to stick with the definitions provided in the dictionary and in the broad context of accepted defintions, SCUBA is a sport though it is not a game whereas football can be a sport but it most definitely is a game.
