We've seen a number of quarterbacks make a huge leap in Year 2 as of late and Bill Belichick believes the New England Patriots have one of their own.

"I think [Mac Jones has] done a great job. He's worked extremely hard. He's got a tremendous work ethic. In all areas, I think there's a dramatic improvement," Belichick said of his quarterback.

"His physical work and conditioning, working on his mechanics, working on his footwork, working on his understanding of our offense, of opponent defenses, of situations. ... He's made tremendous strides. He did a great job last year, but he's starting from a much, much higher point this year than where he started last year. His offseason work has been significant, and I think everyone recognizes how well he prepares and how much further along he [is] than he was a year ago."
