Pretty much all dome teams do this. All this report is doing is distracting people from deflate-gate on SB Sunday.
There's also a bit if this that has been allowed since 2012.
So there isn't much to be worried about here.
Not really. No dome teams are allowed to play music and noise while the opposing team is in their huddle. The Falcons did this repeatedly this year..... Not that it mattered.
At least the Patriots cheated and are in the superbowl. Atlanta cheats and has a losing record.
