Bill Belichick isn't the only New England Patriots coach who leaves no stone unturned.
Among the many adjustments the Patriots will have to make this season, they may have to play games in empty stadiums, as the continued spread of COVID-19 could prevent fans from attending games in 2020.
New England offensive coordinator Josh McDaniels was asked Friday how a fan-less atmosphere may change how he runs the offense, and he gave a pretty revealing answer.

"If it's quieter, I think there's some things you probably have to protect," McDaniels told reporters in a video conference. "You can't change your language. It's like, if we know English, we can't teach them Spanish before Week 1.
"I think you probably will self-scout yourself a little bit more with the television copy (of the game film), because they have the mics all over the place. So, you have to be careful (about) how much of what you're saying is easily detectable. I think it's more about protecting yourself and not giving everything away week after week."
McDaniels makes a good point: A quiet stadium without fans means teams could eavesdrop on opposing offensive coordinators to listen to their play calls, either during the game or while watching the television replay on film.
Under normal circumstances, offensive coordinators usually cover their mouths with their play sheets to prevent teams from reading their lips, but that precaution might not be enough if an in-stadium microphone picks up what they're saying anyway.
It's unclear how McDaniels and other coordinators will guard themselves against this potential subterfuge, but it's no surprise that Bill Belichick's longtime coordinator is considering all scenarios entering an unprecedented season.
