This article sounded a lot like Aaron Hernandez's defense. They cherry picked individual exaggerations and problems they had with some of the specific data, but they failed to logically refute the overall conclusion. For example, it was a 15 year sample size, but they picked out 1 year where the Vikings fumbled less on the road, then asked "did the Vikings cheat too?". They came up with all kinds of reasons why the Patriots fumble less, but didn't explain why it didn't happen until 2007. They say the odds of the Patriots' fumble turnaround aren't 1 in 16,000, like the original article suggests, but 1 in 300, and that number doesn't even account for the timing of the whole thing, so when you throw in the fact that it happened directly after the rule change, which Brady lobbied for, the odds are obviously much less than 1 in 300, even when using your article's math. No matter what article you read, and how you manipulate the stats, the fact remains that the Patriots had a sudden, drastic change in fumbles right in the middle of Belichick's 15 years with the team. This change happened directly after Brady successfully lobbied for teams to be able to bring their own footballs to every game. No other team in the league has done that over such a long time span, and the chances of that happening are far less than 1%, and there are no other known variables that could have caused such a drastic change. The article you gave does not refute any of that. So, are you refusing to accept reality, or are you just clinging to that <1% chance that the whole thing was just a collection of giant coincidences that perfectly fit together?
