From what I have seen of the Bell report that can't conclusively prove anything, it's speculation on what happened.
Also the part in the report where they conclude that the guy handling the footballs somehow was able to juggle 13 footballs and deflate them in about 100 seconds defies reality to me. Can that be done in the atmosphere of getting ready for a playoff game? You will have to prove it to me.
With such a thing as a simple ballbag, no "juggling" needed.
My understanding is one football was normal ...other 11 weren't...so "airing out" 13 balls not even the correct #...
Give an NFL team out of timeouts 100 literal seconds ... including clock time stoppage for first downs...and that's an "eternity" to run 11 plays, if necessary.
If they can run 11 plays with great mobility over a 100 yard field in 100 literal seconds, a couple of guys who are stationary and have plenty of locker room practice (either pregame and/or what they've done EVERY week going back to 2007 or however long they've been employed) would have no sweat accomplishing this 11 football task.
