The New England Patriots confirmed the return of former offensive coordinator Bill O’Brien on Thursday, but amid news of the reunion came a report about the state of the offense and the relationship between quarterbacks coach Joe Judge and second-year QB Mac Jones.

Jones’ frustrations with the offense, specifically with Matt Patricia, who acted as the primary play caller, spilled out on the field several times this season, but the Boston Herald reported there was an issue with Judge, the former New York Giants head coach, as well.

"Mac didn’t like him," one source told the outlet. "At all."

According to the report, while Patricia caught much of the heat for New England’s offensive woes, Judge was the target behind closed doors. 

"Belichick would blast him in practice, and it wasn’t uncommon for Judge and Jones to trade profanity-laced outbursts. Jones’ trust in his position coach was effectively non-existent," the report read.

One source told the outlet that Judge’s persona in meetings "rubbed people the wrong way," while another added that people were simply "frustrated" with him. 

O’Brien returns as an offensive coordinator and quarterbacks coach after two seasons with Alabama but his arrival certainly fuels speculation about Judge’s future with the franchise after a lackluster season serving as quarterbacks coach.

"I am looking forward to working with Bill again," Belichick said Thursday of O’Brien. "He is an outstanding coach and an asset to our staff."
