Bill Belichick had a tough first game as UNC coach. His team suffered a 48-14 loss to TCU at Kenan Stadium on Monday night, and many began questioning whether the 73-year-old coach is the right fit at North Carolina.On Tuesday, former NFL wideout Antonio Brown mocked Belichick by posting a resurfaced video of the UNC coach's 24-year-old girlfriend, Jordon Hudson, helping him at the team's practice on the sidelines.Brown simply added three laughing emojis to the video, which was from April during North Carolina's spring practice camp.Brown played 12 years in the NFL and was part of the Tampa Bay Buccaneers team that won the Super Bowl in 2021. He also played one game under Belichick's New England Patriots in 2019.Belichick coached the Patriots for 24 years and won six Super Bowls. He also won two Super Bowls with the New York Giants as their defensive coordinator.When North Carolina hired Belichick in December 2024, many expected him to be an instant success. However, his tenure at UNC has begun on a disappointing note.Bill Belichick says his UNC team was outplayed by TCU in 2025 season openerNCAA Football: North Carolina head coach Bill Belichick - Source: ImagnAfter UNC's heavy defeat against TCU, Bill Belichick said that the visitors outplayed his team."They outplayed us, outcoached us, and they were just better than we were tonight," Belichick said on Monday.
