Colts balls were at 14 PSI. Close enough to the 13.5 that the officials didn't care. Pats balls were at 12 PSI. Close enough that officials didn't care.
All balls lose 1.5 PSI due to conditions. Colts balls are at 12.5, and deemed within the acceptable range. Pats balls are down to 10.5 PSI, which is the 2 PSI difference from acceptable.

I'm just making #### up obviously.
That's not what happened though, there was no significant loss of PSI on the Colts' balls. If all the balls PSI dropped an even amount, this wouldn't be an issue. Hell, the 12 balls from NE didn't deflate at a common rate so that even points further to tampering.
The only way the Colts balls didn't see a deflation is if there wasn't any. No deflation means they did not see a temperature drop. It's basic physics, people, you can't really work around this.
The reason the Colts balls did not see a temperature drop is because they were checked at halftime at the same temperature they were checked at pre-game - i.e. in the warmth and comfort of the officials locker room.
Therefore, we can surmise that the temperature differential played no role in any loss of pressure, Colts balls or Patriots balls.
Which leaves open the question - what happened to the 2 PSI in the patriots balls?
How much of this is fact? Do we actually know where the balls at halftime were measured and the exact pressures? When people say the Colts balls were in spec, does that actually mean there was no delfation or that they started at the high end and were still within the low end?
we don't know, all we can do is surmise based on the (shoddy) information at hand.
With what we know now, there's at least 1 psi unaccounted for from the Patriots balls, possibly over 2 PSI (depending on various measuring conditions).
Those PSI could be from the patriots staff submitting under-inflated balls to the refs (intentionally or not), who failed to fully inspect them, or the PSI may be missing due to post-inspection modification.
Got it, thanks. It would be nice to just get the details, then again, you know where I stand on this, non-issue IMHO especially since the balls were replaced.
yeah I know. I think it's a huge deal based on the patriots lack of fumbling per the article cited above. The sports science made no mention of ability to hold onto a softer ball...they said something about "grip strength", but didn't go into detail about what grip strength is, how it is measured, or why it's important.
A slightly softer ball will not make a difference in every game, but over the course of a few years, you bet it would show an effect.
That study is full of holes. It uses fumbles lost, instead of total fumbles... so unless the deflated ball helps the Patriots recover their fumbles it doesnt make much sense. The Falcons have a better plays per total fumble over the time period.
I know he's trying to claim that as an outdoor team its still an outlier, but he hasnt controlled for where games are being played (only half your games are at home) and is making a lot of assumptions about fumbling outdoors. The bottom line is the Pats run a ton of plays. They dont lose as many fumbles as you would assume. Could that be great coaching? A QB deft at recover fumbles? A million other things? I think yeah.
yeah I know. I wish the author had done some of the analysis a little differently. I'm sure someone will get on it. i'd like to do it, but my boss expects me to do at least a little work today.
Here's how I'd improve the data:
1. look at RB/WR/TE fumbles only. QB's losing the ball due to blind-side hits, or poor snaps, or mike vick not tucking the ball when he runs...those shouldn't be considered.
2. control for team A vs opponent, home and away...come up with sometihng like Atlanta Falcons fumbled 5 less more per hundred carries than their opponents, Buffalo Bills fumbled 10 times more per hundred carries than their opponents, something like that. This would completely take venue out of the occasion.
If you could show that the Patriots backs fumbled less than opponents, regardless of location, I think that would be pretty strong.
Still, the data as shown is pretty compelling, it just needs to be explored further.
