The demand for precision has gotten a bit out of hand, I think. Back in
2008, when I first joined the EvC community, I was caught up in the idea that there had to be purity in sports, and that it was an unfair assessment of an athlete's or a team's performance if something other than their athletic ability (equipment, environment, etc) impacted their success.
But now, several years later, with all the instant-replay and the the concussions and the controversies about things I didn't even know mattered (like PSI), I've kind of gotten sick of hearing about all the underhanded ways people have come up with to get an edge in a competition.
Not to drag this too much into politics, but this goes back to the fundamental question of how to balance free-market vs regulation. Allowing some experimentation with the parameters of the game leads to innovations (that's how American football got the forward pass, the two-point conversion, etc); but too much "innovation" cheapens the experience for the players and the spectators.
A sport that has a strong following and a rather long history, like American football, is bound to accumulate regulations over the years, but you have to wonder whether the regulations and concomitant controversies will eventually become so stifling that the game loses its appeal.
