Again, just to clarify, I am not speaking anything about the 90-100 seconds in the restroom.
I am simply stating the facts which caused the NFL to look deeper into the investigation in the first place, which include the following TWO situations that coincidentally (or we hope) took place:
1. The fact that the balls were underinflated/deflated/lost air via nature---this in and of itself would be considered "bad," but when combined with reason #2, appears much worse in the eyes of those who believe that something funny may be going on. Reason #2 provides the term "opportunity."
2. The fact that the ball guy chose (or was forced...again, by "nature") to use the restroom during the very small and inopportune time which occurred not in the hours prior, not in the hours after, but during a very small 10-15 minute window when his sole purpose was to take the balls from the officials' locker room, and go directly onto the field. Again...I'm giving him the benefit of the doubt by suggesting that a 10-15 minute window even existed. It may have been much less.
You don't have to be a genius to realize that these 2 situations, when COMBINED, have given the league something more to look into, which is all I was stating. As far as whether or not the deflation of balls may have occurred within the small 90-100 seconds in the bathroom--it obviously provides enough doubt to where the NFL is concerned, so that's all that really matters.
