Evidently, there appears to be bad blood between North Carolina and the New England Patriots under Bill Belichick's rule as head coach. So much so that it took North Carolina's social media team a minute too late to celebrate former QB Drake Maye on Monday.

This, after Maye, QB of the Patriots, led them to an upset win over the undefeated Buffalo Bills on Sunday. On Monday, former North Carolina coach Mack Brown took to social media, seemingly taking a subtle jab at the program when he celebrated Maye.

“So Happy for Drake. Fun to watch him win last night in Buffalo like he did so many times at UNC,” Mack posted. “Love ❤️ and Appreciate you my friend! Keep it rolling!”

According to insiders, Belichick told UNC's social media team to not post anything related to the Patriots. Brown coached the program from 1988-1997, and then again 2019-2024. Ultimately, in November 2024, Brown was fired as head coach at UNC.

That December, Belichick was brought on as head coach. In 2023, his long tenure as Patriots head coach ended very bitterly and he appears to carry resentment to this day.
