Boykin came into the 2014 season with the expectation of serving as the Packers' No. 3 wide receiver behind Jordy Nelson and Randall Cobb. However, after a poor start that saw him catch just two passes over the team's first three games, Boykin ceded his playing time to rookie wideout Davante Adams. Boykin never recovered, catching just one more pass the rest of the year.
As a result, Green Bay chose not to extend Boykin a restricted free agent tender, thus making the receiver available for any team to sign. After several weeks sitting on the open market, the receiver-strapped Panthers finally pounced.
Though Boykin disappointing last season, he has shown signs of being an effective receiver in the past. In 2013, he caught 49 passes for 681 yards and three touchdowns in relief of the injured Cobb and James Jones.
