DeflateGate Update 10: NFL’s football-making company rep says of Belichick’s description of deflation, “That’s BS!”

More and more experts on footballs are coming out of the woodwork to call out Patriots head coach Bill Belichick’s understanding of ball air pressure.

DeflateGate rolls on as a representative of Wilson, the official football-manufacturer of the NFL, said that Patriots head coach Bill Belichick’s explanation of how footballs lost their air pressure at the AFC Championship Game was “BS.”

On Saturday Belichick held a surprise press conference in which he explained the process by which footballs lost air pressure after being exposed to different atmospheric conditions – moving from a warm room of 70-plus degrees Fahrenheit to about 51 degrees Fahrenheit in the freezing rain.

Boston.com met with members of Wilson to learn about the process of inflating and deflating the football. One rep, Jim Jenkins, heard what Belichick had to say and gave his own thoughts on the matter.

“Not going to say (what I want to say),” Jenkins said. “That’s BS. That’s BS, man.”

When asked how he believed the Patriots game balls could have been deflated, Jenkins shrugged and said, “Only the New England Patriots know.”

Jenkins then explained that it would take “maybe in a year or two” for the air pressure to change after being introduced to different environments thanks to the design of the balls. But he added that a ball’s pressure could change quickly change if placed in a freezer and then unfrozen.

“All we know is what we can control is when it leaves the factory it’s within an NFL spec, within the PSI of 12.5 to 13.5 pounds of pressure for every single NFL team,” according to Wilson’s director of experiential marketing Molly Wallace.

With scientists like Bill Nye and now even the manufacturers themselves calling out Belichick’s explanation of how the footballs were deflated below NFL-permitted levels without deliberately altering it, it appears DeflateGate still has some air in it.
