Not brilliant at all just fact. As long as the playing field is the same for all why should anyone cry over a new ball.
Your thinking is plain simple and foolish.
Let me ask you this. Why do professional teams cover outdoor playing fields before the game when it is raining or snowing. Why??
Why to ground crews try to make the playing surface as good as possible in games like baseball and football for instance?
Why does a major league grounds crew try to get rid of all the little stones and pebbles from real soil infields?
Why do these people make efforts to keep the fields playable for the players? When you finally think of the answer to those questions, you may begin to know why a decent "unslippery" ball should be furnished...... if at all possible!
If you think slippery balls are great for the most important game of the football season then why don't they just go and smear Vaseline on the balls before the game? It would be the same for both teams....... that satisfies your simple rationale.
Too sum it up.......... efforts are made through the decades to offer to the players an excellent playing surface....... efforts should be made to give them a good ball to play with. Plain and simple!
"As long as the playing field is the same for all why should anyone cry over a new ball."
Anything that introduces an element of luck advantages the less skillfull team and disadvantages the more skillfull.
It may appear that a bad playing field should affect both teams equally and fairly. However, as with so many "intuitively obvious" things, that isn't the case.
In my sport, for instance, bad officiating can give the 2nd through 6th or 7th best competitors a chance to win a competition, where with very good officiating they would have no chance.
