I love football. It has been my favourite since i was a little boy. What i like about it is it's specialization. In other types of sport, let's say baseball, a player need to be good at everything to be able to stand at the field, from catching, throwing, running, etc.
But not in Football. In football, a player only need to have 1 skill to be able contribute on the field. If you're good at running ? be a running back, if you're good at catching ? Receiver will you go. Football exploited one special talent of each athletes and the combination of these talents, create a strong team dynamic as a whole
