According to NFL commissioner Roger Goodell, the league only measured PSI data via "spot checks" and not because it wanted to conduct scientific research.
Two weeks ago, Pro Football Talk reported that the NFL could release a summary of the PSI numbers collected during the 2015 NFL season. Naturally, the hope in New England was that the data would once and for all show the league office that footballs can in fact deflate due to atmospheric conditions.
Alas, we are talking about the NFL; masters of spinning the narrative to put themselves in the best possible light while simultaneously throwing mud at the league's most successful franchise.
