Are you kidding me? It's the only option they have,
1) They already announced that they checked the balls before hand and they were in range and there were no chain of custody issues.
2) If it shows now that the balls were below 12.5 PSI, how did it happen?? They already said there was no tampering ( i.e. chain of custody) so it leaves natural causes and the IGL which blows up their entire premise for Deflategate... If there was no deflated balls, there is no reason to go after a phone..etc etc....
If there was ever a time for Mr. Kraft to stand up, it is now. It is a perfect scenario for him to say, " see we didn't deflate the balls, it was the weather that caused it. I want all the numbers released from the Steeler-Giants game."......
Like that's ever going to happen.................
