A new book written by ESPN's Seth Wickersham about the Patriots' dynasty details the tension between key figures in the franchise, including owner Robert Kraft and coach Bill Belichick.
At one point in 2018, Wickersham reports, Kraft called the team's longtime coach the "biggest f------ a------ in my life."
"As for Kraft, in late September, he was in Aspen [Colorado] for a conference and bumped into a few friends in the hotel lobby early one morning. He told them he was leaving later for Detroit, where the Patriots were playing their next game. 'I hate leaving here,' Kraft said, per ESPN.
