At 4:30 p.m. Sunday, their next playoff game will start. Some three hours later, Kraft will either have another home playoff game to watch or the unenviable duty of patting disappointed players on the back.
"I'm always a little uneasy," he said.
Whatever happens, the Patriots should be contenders for a long time. Young players are making major contributions and Tom Brady has a $72 million, four-year contract extension that starts next season.
He'll be 37 by the time it expires and said before the deal was made that he wants to play 10 more seasons.
The contract agreed upon three days before the season opener was "one of the great strategic things we did," Kraft said. "I wonder if Tommy would have had the year he had if we hadn't taken the contract (issue) away and put it to bed. ... I think that was a real big move in giving him peace of mind."
Brady had one of his best seasons, perhaps surpassing his 50 touchdown passes with just eight interceptions in 2007 when the Patriots went 18-0 before losing the Super Bowl to the New York Giants 17-14.
He is a favorite to win his second regular-season MVP award after throwing 36 touchdown passes and four interceptions.
"It's a tremendous amount of money," Kraft said, "but he, obviously, is worth it."
