Only for special teams' plays.
Otherwise, each time supplies balls for their own offenses.
In fact, guess who it was in 2006 that was lobbying the NFL so that the offenses could indeed supply their own footballs? (Yup, Tom Brady...and another little-known Q named Peyton)
So teams have been supplying their own offensive footballs since 2007...exactly coinciding when the Pats' fumble ratio suddenly - year-in, year-out - began going off the charts! (Some of those years, the Pat defense fumbled more than the Pat RB!)
Brady's completion % suddenly spiked upward starting in '07!
Since the balls were measured with different equipment, at different times, in different conditions....you have no base-line to use in proving or disproving this “evidence” the NFL used. The first report the NFL released lied about the PSI numbers....there’s no there, there. That’s why this article is exposing that most of the other NFL teams know that deflategate was a farce.
