VIDEO: Bill Belichick Appears to Have Multiple NSFW Comments During Patriots' Loss to Ravens

The New England Patriots have been the darlings of the NFL world after their 8-0 start to the 2019 season. While that's no small feat, it did come against average competition. Their first test came during primetime on Sunday night against the explosive Baltimore Ravens. Ever since kickoff, the Patriots struggled when trying to stop dual-threat quarterback Lamar Jackson. The second-year signal caller proved to be more than Bill Belichick could handle. During the opening drive of the game, the Patriots were called for an offsides penalty. NBC cameras then set their focus on Belichick, who appeared to mouth a phrase that no kid should use at school on Monday.

Belichick's frustration only increased as the game went on. During the fourth quarter, the Patriots head coach was seen talking to a referee on the sidelines and after not hearing an answer he liked, uttered yet another explicit word.

Belichick is often known for his stoic demeanor both in press conferences and on the field. But playing the Baltimore Ravens obviously gets under the future Hall of Famer's skin.
