The urinal story is made up? It's from the interview with the deflator.
The intercepted ball was a souvenir ball for D'Qwell Jackson. He could've sat on it, ate it, poked holes in it, thrown it in the garbage, etc. The NFL rule regarding deflation/inflation is for balls being used for the game itself. Did the Colts measuring that one ball to confirm their suspicion magically deflate the other 10 balls?
