Its not even confirmed that Green Bays footballs were way overinflated....Rodgers just said that he likes them on the higher side
The only confirmed situation is that New England has used deflated footballs and the chart pretty much has one huge outlier...just so happens to be New England with such a lower amount of fumbles than the rest of the league...Guess we will find out in the coming years if the pats keep up the crazy non-fumbling rate..
