What about the refs? Unlike the players they always have to be near the ball so cover the whole pitch and still have to be able to watch the actions of players.
I said this before – the refs cover a lot of ground, similar distances to the players, but it’s in a more controlled way. Lots of sprints, for sure, followed by recovery, but they don’t tend to do so much in the way of direction changes, pushing off in different directions at full tilt, twisting, etc.
And also (and trust me- this gets easier, not harder as you go up in standards) a decent ref can read the game and make moves to be in a certain area in preparation for the ball getting there rather than following it there. At lower / local league level the ball can go from end to end to end unpredictably based on no-one having the ability to control the ball and keep possession for more than a microsecond. Couple that to the 5’s and 9’s having only got in from the night club 3 hours ago and still fancying a punch up, and they were physically the hardest games i ever reff’ed, doing repeated 75 yard shuttle runs just to be vaguely close to the action when finally it all kicked off!!
Then get a load of abuse for doing it.
Of course. But you get travel expenses, and a pint afterwards, and everyone’s your mate, at least they are for as long as it takes them to realise that no you can’t be bribed and that yellow card will be being reported to the county FA in the morning and they will be getting a fine for it.
