So, if the football weighs something over 400 grams, what is the expected deviation of the football's weight by manufacture, and by environmental change?

The question could be relevant IF...
...the officials failed to weigh the Colts' footballs...

'Cause if they DID weigh the Colts' footballs as well, then to have all 12 Colts' footballs in sync -- and almost 90% of the Pats' footballs out of sync...

...that'd be difficult to pin the blame on the manufacturer -- assuming both teams get their balls from the same source. Right?

I agree, absent other facts. In my post I did say it would be odd for only the Pats' statistics to vary on the downside.

Whether deliberate deflation, with all of the videos around is the answer, or there's some other explanation, I don't know.

“assuming both teams get their balls from the same source.”

I don’t think you could just assume that, and if they did you couldn’t assume it was the same production run. Were talking about 17 thousands of an Oz here...
