Kiko Alonso: A-
This season will go down as the year the Legend of Kiko was born. The second-round draft pick did not waste any time stepping into the starting middle linebacker role. He was given a lot of responsibility by the coaching staff and played very well.
He finished the season third in the NFL in tackles with 159 and added two sacks and four interceptions to that impressive total. He should be considered a favorite for Defensive Rookie of the Year. He would join Shane Conlan and Jim Haslett as the only Bills to ever win the award.
Manny Lawson: B+
Manny Lawson signed with the Bills as a free agent and played well his first season in Buffalo. He had 73 tackles, four sacks and capped the season off with an interception on Tom Brady.
Arthur Moats: C+
Arthur Moats had the best season of his career with 54 tackles and provided good depth for the Bills linebacker corp, but he is not a starter for this defense. Along with the offensive line, improving the talent at this position should be a top priority for the Bills' front office. Moats has the talent to be an excellent reserve linebacker and, if he is able to stay in that role, it would help this group.
Nigel Bradham: D+
Nigel Bradham was expected to step into a starter role at the beginning of the season, but he struggled. He had his best game of the season in Week 17 against New England with 10 tackles, but he didn't make a big impact before then. He finished the year with only 51 tackles.
