Perhaps it's just that I'm sick in bed but this was the best written analysis on the ball pressure readings I've read the far:

Good fodder as we look forward to Kessler destroying the report in court.
Hesitate to post here again, but the debunking of the scientific analysis is pretty good. What's particularly interesting is how well Wells/Exponent hid the scientific prejudices (completely fooled me, which is no great shakes) and how anyone with real brains (like a university professor) could miss all that.
One thing that makes this re-analysis even more damning is the incredible variation in pressure gauge readings, for example:
1. The difference between the logo/non-logo readings at halftime should theoretically have been identical for each ball, but they ranged from 0.30 to 0.45 (with one outlier at 0.08). That's a .15 psi difference just from reading the same gauge over and over.
2. The Colt's field measurement of the Patriot's ball
using the same gauge 3 times showed: 11.45, 11.35, 11.75 -> a 0.40 variation just in 3 consecutive measurements
3. Exponent's own shady test of "similar gauges (not)" in the lab showed a variation as much as .65 psi between them. The gauges used by all parties probably had a high degree of inaccuracy.
So, if the uncertainty ranges are factored into these reports, it looks even worse for Exponent. I understand why he didn't do this because to insert ranges for every analysis would have made reading the conclusion difficult.
Every analyst should want to see Exponent's people on a stand and cross examined under oath. That would be a TV show worth watching. Ain't gonna happen.
{EDIT: You know, time is a wonderful thing. Enough has passed that I, for one, don't really care about the manufactured "scandal" any more. It's really fading. Interestingly, I care more about the manipulation of facts than whether or not McNally deflated footballs. So, even if the footballs were deflated, why does the NFL specifically prejudice the report to ignore facts and science in order to come to a conclusion?}
