That clip has taken Brady out and replaced with Mel Gibson.

Are you sure? I watched it on netflix recently and it was Brady and I was pissed. The clip on youtube it was replaced with mel gibson but I think that was likely a Patriots fan being awesome.

Feel free to ask the brains at Exponent who did the report. Here are their emails. I am sure they will love getting emails about what an MIT professor thinks of their work

I have credentials in a technical profession and I have also been an expert witness in civil litigation. All of my work is subject to rigorous peer review by colleagues in my firm who have the necessary qualifications to practice in our area of expertise. I am a member of two professional societies and am bound by a Code of Conduct and Standards of Practice.

I could never get away with the nonsense these guys pulled in this case. It is fair to wonder what quality control measures Exponent employs and what kind of external standards these experts are bound by. The sloppiness in their work and their refusal to acknowledge blatant errors are indicative of a complete lack of accountability within Exponent itself and by whatever academic and professional affiliations these so-called professionals credit themselves with.

One other thing - I have a professional responsibility to ensure to the best of my ability that others do not misrepresent or attempt to otherwise misuse my work. I am aware of at least one blatant misrepresentation of Exponent's findings in the Wells report. This is another professional failing on the part of Exponent.

The professionals at Exponent may say their feelings are hurt by unjust criticism; in reality, they should be ashamed of themselves for sacrificing their integrity for money. Their willingness to do so makes them ideal partners for Roger Goodell's NFL though.

Christ... this will never end.

@Zeus, just so you know, I have a man crush on you.

It actually was measured 3 times, by the same person using the same gauge, giving values of 11.35, 11.45, and 11.75 psi. This does indeed average to 11.5 (and 11.32 is predicted), but it also shows that there is a tremendous amount of ERROR in using those gauges.

[...]the alleged 0.3 psi difference ALSO vanishes like a fart in the wind even if Walt Anderson actually used the gauge that he thinks he didn't use, because 0.3 psi is way less than the error bar for using one of these gauges one time for measuring each football, as evidenced by the 0.4 psi range of values obtained for testing the intercepted football.

I suspect you are confusing the error bar for an individual measurement (measurement error) with the error bar for a mean (standard error). The standard error for the mean is related to measurement error (along with random variation and other variables which give a sample its variation as represented by standard deviation), but you need to divide measurement error etc. (i.e., the standard deviation) by the square root of the sample size in order to get the standard error for the mean. In other words, the standard error of the mean can be MUCH smaller than the measurement error. This is why sample size matters when estimating population means from sample means. Sample size cuts through noise when estimating means. Sample size cuts through measurement error when estimating means.

A review of a good introductory statistics text will help you see my point. I recommend Jacob Cohen. Playing around with this applet can be even better: Sampling Distributions.

Please note that I "liked" your post, and my post is not intended as an insult to you. If I did not think you were smart, I would not make this effort to inform you. (I myself am not very smart, but I know a little something about applied statistics.)

Best wishes.

(Edited to be more precise about variation, variance and standard deviation. Also error bars are often about two times the error to provide a 95% confidence interval. I'm rusty!)

Great post.

Don't forget about that Princeton professor that signed off on the report.

wait
pump the breaks

are you telling me tom brady didn't let air out of my tires last night, and that the air pressure light turned on because it was chilly out?

are you SURE like 100% sure, that Tom didn't drive to my apartment?

I'm pretty sure it was Mcnally. That fat **** is driving all over New England doing this. My Jeep was hit last week.

Last time I checked it didn't failed, Tom Brady served 4 games. The teams that should have used this handicap in their benefit failed to do so, they lost an opportunity.

100% failed? No it 100% succeeded. Go to hell and the owners got their power confirmed and upheld in federal court despite admitting "there is NO evidence". This was never about the balls that was just an excuse. This was always about taking the pats down a notch and then having the right to do so validated.

Pretty obvious that it went like this:

Vincent: We can get Tom Brady too!
Lawyers: We can also chip away at the CBA.

Goodell: Go for it.

Stop giving Exponent an excuse that it was sloppiness or an error. They had to arrive at a predetermined result being paid by a client, so they made a "mistake" here or there. Never in favor of Brady.

Kinda like how the dash/body cams of controversial shootings are somehow never on or get "accidentally" deleted. Call it what it is: It's straight up destruction of evidence.

Observer said:

This is well and good but ultimately pointless because as Deus said, this was never about the truth. This was a corrupt group of owners trying to bring down a team by character assassination. You can watch the NFL but you better know what you are watching - a corrupt league that cannot stand the success of the Patriots. Don't be angry or surprised when there is enough lopsided refereeing to prevent the Pats from winning or if there is another "cheating" allegation. That is just the nature of the game.

Yeah one of our games at home this season, the announcer said the Communications with the QB was down, then he said he doesn't want to fan any conspiracy theories, but this happens often at Gillette. Later it was determined that it was the battery on the QBs headset but the announcer didn't apologize for fanning conspiracies.

Zeus, it's not really a fair fight. Clearly, Paul R. Johnston, CEO of Exponent, is no match for the Greek god of thunder and king of all gods on Mount Olympus.

Johnston is a structural engineer with no integrity. He can build a bridge but can't inflate a bicycle tire. He's got two degrees from Stanford and is butt hurt that Stanford hired the wrong Harbaugh.
