Langford, 31, is a former third-round pick of the Dolphins back in 2008. He spent four years in Miami and played three seasons for the Rams before signing a four-year, $17.2 million contract with the Colts back in 2015.
Langford was set to make base salaries of $4 million (2017) and $4.2 million (2018) over the remainder of the contract when the Colts released him with a failed physical back in August. The Saints just recently signed him to a contract, so this is a bit of a surprise.
In 2016, Langford appeared in eight games for the Colts and recorded 10 tackles, no sacks, a fumble recovery and two pass defenses.
Tapp, 32, is a former second-round pick of the Seahawks back in 2006. After four years with the Seahawks, Tapp signed a three-year contract with the Eagles as a free agent in 2010.
Tapp played a year for the Redskins before signing on with the Lions in March of 2014. Detroit later brought him back on a one-year deal before he eventually caught on with the Saints.
Unfortunately, the Saints cut Tapp loose coming out of the preseason as they trimmed their roster down to 53 players. New Orleans just re-signed him a few days ago.
In 2016, Tapp appeared in all 16 games for the Saints and recorded 17 tackles, 0.5 sacks, and one fumble recovery. Pro Football Focus rated him as the No. 43 edge rusher out of 109 qualifying players.
