Highlights: Any discussion of undrafted free agents starts with Butler, who burst onto the national scene with his Super Bowl interception. He has been one of the Patriots' most consistent defenders this season and probably is going to be in the Pro Bowl discussion. It can sometimes be hard for a young player to edge out more established stars, but Butler has been impressive this year and has earned a place in the conversation. What a story: from West Alabama to tryout player to Super Bowl hero to No. 1 corner, all in the span of a year. ... Amendola has thrived in his third year with the team. ... Elsewhere, Kline is the latest in a line of developmental prospects along the offensive line who have worked their way from undrafted to starter. He played at Kent State. ... As for this year's undrafted class, Andrews, of Georgia, was the top player through the first nine games of the season. His steady play at center helped the team navigate some injury issues, and he was the only player to play every snap through the team's first nine games. ... Meanwhile, Coleman has been the team's No. 3 cornerback after he rose up following a string of injuries and poor play from others. The Tennessee alum has missed the past three games with a right hand injury but is on the cusp of a return. ... King, who attended Auburn, has been one of the surprise players of 2015. He is tied with Pro Bowler Matthew Slater for the team lead with 10 special-teams tackles. He opened the year on the practice squad.
