Arenas did not play in the NFL in 2015. He was signed by the New York Jets on August 11 but was waived by the team on August 30. The cornerback was actually signed by the Jets after the team released I.K. Enemkpali.
The Kansas City Chiefs drafted Arenas 50th overall in the 2010 NFL draft. He appeared in 47 games with the Chiefs, starting in 12 games, but never developed into the cornerback they were hoping. He registered 136 total tackles, four sacks, 22 passes defensed, two interceptions and three forced fumbles with the Chiefs.
In 2013, Arenas was traded to the Arizona Cardinals in exchange for fullback Anthony Sherman. In Arizona, Arenas played in all 16 games but only registered 12 total tackles and a sack. He signed a one-year deal with the Atlanta Falcons in 2014 but only appeared in six games. Arenas recorded 10 tackles and a passed defense in Atlanta.
In addition to playing cornerback, Arenas can also contribute on special teams. In his career, Arenas has recorded 106 punt returns for 1,035 yards and 73 kickoff returns for 1,541 yards.
Arenas has a chance to stick with Buffalo because of his ability to return punts and kickoffs but he’ll have to really impress Buffalo’s coaching staff. At cornerback, the Bills have their first five spots locked up between Stephon Gilmore, Ronald Darby, Nickell Robey, Leodis McKelvin and Mario Butler.
