As said over in the thread in the main forum, I don't see why people are all "woo-yay! They didn't write the PSIs down! It's all BS!"
First, Blandino explicitly said the refs (Walt Anderson himself, actually) used a gauge. So we can all forget about all the "squeeze test" theories. (You can of course say Blandino is lying, but it doesn't really matter. The NFL has made it clear their official position is that the balls were gauged.)
Second, I don't see any big deal with the PSIs not being logged. Anderson saw the numbers on the gauge. He can testify to Goodell what numbers he saw. Goodell will of course believe him.
But even if this were in an actual courtroom this would still be evidence. Anderson would testify that that the balls were all in the legal limit. He may well even remember a specific pressure or two if a ball were an outlier. He'd be cross-examined. And then the fact-finder (jury, or judge in a bench trial) would have to decide how much to believe him. And if they decide to believe him, then that's pretty much as good as if there were a log.
And we're not talking about a real courtroom -- we're talking about Goodell and the league investigators, who are far more biased/corrupt than anything in a real courtroom. The lack of a log means nada.
