5 NFL free agency signings that were absolute disasters

Monday kicked off the start of free agency as the legal tampering period began. We've seen some top players like Brandon Scherff, DJ Chark, Laken Tomlinson, JC Jackson, Carlton Davis, etc., all agree to terms on new deals. Free agency is a time for teams to spend big and often overpay for free players on the market as they look to improve their teams for the future.

Sometimes, these signings don't pay off (literally), and teams overpay for players that have little impact on their teams. Here are some of the worst free-agent signings in NFL history.

The worst NFL free-agent signings of all time

#5 - Javon Walker, Raiders

Javon Walker inked a six-year $55 million deal with the Oakland Raiders in 2008 that included $27 million in the first three years and $16 million guaranteed. Before signing his massive contract with the Raiders, Walker only recorded two 1,000-yard seasons in his six seasons in the league. In November 2008, Walker announced that he'd miss the rest of the season due to injury. Walker played in eight games for the season and had 15 receptions for 196 yards and one touchdown. For the 2009 season, Walker played in only three games and had no statistics. The team released him on March 8, 2010.

#4 - Nnamdi Asomugha, Eagles

The Eagles inked Raiders cornerback Nnamdi Asomugha to a five-year $60 million deal in 2011. Before the signing, Asomugha made three consecutive pro-bowls and was regarded as one of the most shut-down corners. In the two seasons Asomugha played with the Eagles, they went 12-20, and he was released before the third year of his contract after losing.
