So, in addition to Neil DeGrasse Tyson, there are also scientists coming out in support of Belichick's answer to the problem. While these scientists are all employed in the Boston area, that is not a guarantee of bias, just like Bill Nye being from Seattle is a guarantee of his bias in saying Belichick is wrong. According to these scientists:

Mahadevan estimated that a drop from 80 degrees to 53 degrees would cause the pressure to fall from 12.5 to 11.9 pounds per square inch.
Not quite the 2 pounds per square inch, but he also used the ideal gas-law equation which does miss some tiny real world factors that could affect the outcome.

Also, there is some complaints I have found about Neil DeGrasse Tyson's calculations, claiming he was confusing gauge pressure and absolute pressure. However, he still returns an answer that the air used to fill the balls must be around 90 degrees to get the requisite 2 lbs drop in pressure. Rather, if only temperature and rubbing the balls down, there would have been an observed pressure decrease of 1.2 lbs, still shy of the required 2lbs.

So, while they deny NdGT's answer, they do agree that the ideal gas law is not quite enough to explain the discrepancy. Also, if the balls were tested inside, in the same location they were initially tested, they would be heating up again being inside and regain the pressure they originally had, with the exception of if they lost some air molecules (which Wilson said would require defective bladders on 11 out of 12).
