Where it matters most is in Tournaments. Imagine EVERY play when the other coach either scooches his players a yard or so closer to your ball carrier or a yard or so away from your defenders. Those yards add up and makes a HUGE difference over the course of a game with a trophy or Championship attached to it.

The RAIDERS wet down their homefield once upon a time to get an edge; Green Bay ordered an Ice Storm against Dallas to get an edge; New England only swept away the snow on their FG attempt, etc. Sportsmanship is overrated. Just win, baby!!!!
