It's already been addressed that kickers use separate balls, so putting that aside...
Bingo. The league has been very flim-flammy in its handling of this whole deal:
"Who certified the footballs before the game, and how confident is the league that the proper protocols were taken by the game officials? All we've heard via the leagueâ??s statement: "Prior to the game, the game officials inspect the footballs to be used by each team and confirm that this standard is satisfied, which was done before last Sundayâ??s game." A few more details would be nice.
Precisely what was the PSI reading of each of the Patriots' footballs at halftime? Numerous reports have put it at more than two PSI below the acceptable range, other reports have said it was closer to one. Give us the exact data. And while we're at it, what were the Colts' readings at halftime?"
And while I agree that some deflated footballs don't account for a 45-7 margin of victory, I do think this is a big deal. Again, quoting the above article:
"If rules governing the actual ball arenâ??t important, then what are we all doing here?"
