With free agency dying down in the NFL, ESPN recently decided to put together a list of each team's worst ever free agent signing. There are several to choose from for the Indianapolis Colts, but the one that they decided on was the signing of safety LaRon Landry a few years ago.
Colts general manager Ryan Grigson brought Landry aboard in 2013 with hopes he would recreate his productive season with the Jets. Instead, Landry fell short (no interceptions), was suspended four games for using performance-enhancing drugs and eventually was released after two seasons with the team.
The signing of Landry certainly was a disastrous for the Colts. In 2013, Indy signed him to a four-year, $24 million deal based largely on the fact that he had a Pro Bowl season with the New York Jets in 2012. Landry only made it two years with the Colts before being cut, however, playing in 23 games in 2013 and 2014 and starting 18 of them. He recorded 134 tackles, 2.5 sacks, and two passes defensed during those two seasons. He really struggled to handle the starting safety duties, and a bad 2013 campaign was followed up by an even worse 2014 season as Landry again failed to impress on the field but also received a four-game suspension for PED use. Upon his return from the suspension, he lost his starting spot (though he got it back near the end of the year). After he was cut by the Colts, he received a ten-game suspension for PED use, and then shortly thereafter received an indefinite suspension. Furthermore, during his time with the Colts, Landry reportedly "didn't want anything to do" with many of his Colts teammates.
There have been several free agent moves during the Ryan Grigson era that haven't worked out, but there's a good case to be made that the signing of LaRon Landry was the worst of the group. And if you ask ESPN, the signing of Landry was the Colts' worst free agent signing of all-time.
