In honor of the 20th anniversary of NFL free agency, we’ve already listed the Top 20 free-agent signings of all-time. We wouldn’t be doing our jobs if we didn’t list the 20 worst free-agent signings, too. For every Drew Brees, there’s an Albert Haynesworth. Here’s our list of the 20 worst free-agent signings all-time.

It was the biggest contract ever given to a defensive player in NFL history and it was one of the worst. Haynesworth inked a 7-year, $100 million deal, bristled about being misused in a 3-4 defense, failed a few highly publicized “fitness tests” in training camp, and gave next to nothing in 20 games with Washington. He was gone by the end of the 2010 season, with just 6.5 sacks in his Redskins career.

After a few good seasons in Arizona, the Chargers backed up the Brinks trucks and signed the 6-2, 230-pound Boston to a seven-year, $47 million deal, with $12 million guaranteed up front. Boston’s Chargers career started off well, catching 70 passes and scoring seven touchdowns in his first season in San Diego. He was ultimately traded to Miami a year later after feuding with coaches and serving as a locker room cancer. There were PED issues, he dropped passes, he reportedly fell asleep in team meetings and he fought with everyone.

Two of Deion’s free-agent deals — with San Francisco in ’94, with Dallas in ’95 — made the Top 20 free-agent signings list. His 7-year, $53 million deal — at the age of 33 — with the Redskins in 2001 was one of the worst. Sanders played one season in Washington before retiring and eventually coming back for one last year with the Ravens.

Archuleta had several strong years in St. Louis and leveraged those campaigns with the Rams into a massive payday from Daniel Snyder in Washington. In ’06, the Redskins signed Archuleta to a 7-year, $35 million deal, with $10 million guaranteed. He played one season in Washington, was benched, and was a Chicago Bear the next year.

Brown parlayed a Super Bowl XXX MVP award into a mega-contract from the Raiders the following March. He never lived up to expectations, lasting just two seasons in Oakland after signing a five-year deal. He was ultimately waived by the Raiders.

Walker got $55 million over six years, with $16 million guaranteed in 2008, the March after he was released by the Broncos. In two seasons with Oakland, he caught 15 balls. Walker collected $21 million in just 11 games in the silver and black.

As the Raiders paid Javon Walker big money in 2008, the Jaguars were inking a similar ill-fated deal with the former Raider, Porter. The one-time Raiders star signed a six-year, $30 million deal with $10 million guaranteed. He played one season with the Jaguars and caught just 11 balls.

After three straight Pro Bowl seasons with the 49ers, Jeff Garcia had a rough 2003, getting released after a 7-9 season in San Francisco. Sure enough, the Browns stepped up to the plate, offered him a 4-year, $25 million deal. He was with the Detroit Lions by the following season.

Odomes went to four straight Super Bowls and made two Pro Bowl teams with the Buffalo Bills. He then cashed in on the new era of free agency by signing a big multi-year contract with the Seattle Seahawks. He never played a game for Seattle due to a knee injury, but collected two years’ worth of pay and a $2.2 million signing bonus.

Alvin Harper was a two-time Super Bowl champion and a key contributor to the early '90s Cowboys dynasty, but he wasn’t much in Tampa Bay’s creamsicle uniforms. In two years, he did next to nothing, but collect checks from a 4-year, $10.6 million deal.

Delhomme was coming off a disastrous year in Carolina when Mike Holmgren and Co. decided to commit two years, $7 million to him. He beat Seneca Wallace out for the starting gig in training camp, but went just 2-3 in five games with the Browns. He was released the following off-season.

Smith had a great seven-year run with the Buffalo Bills and cashed in when he hit free agency in 2000. He signed a five-year deal north of $22 million to be the top cornerback in Chicago. He played one season with the Bears.

A four-time Pro Bowl receiver with the Falcons, the Browns inked “Bad Moon” to a five-year, $17 million deal that made him the highest paid receiver in NFL history at the time. Rison caught just 47 balls and was released at the end of the ’95 season.

Walker had a few good years in Oakland before Marv Levy, the GM of the Bills at the time, decided to ink him to a five-year, $25 million deal with $10 million guaranteed in Buffalo. Walker battled injuries for a few years, didn’t do anything spectacular, and was released before the 2009 season.

After several productive years in Miami and a strong 2002 season with Washington, the Broncos stepped up and inked Gardener to a seven-year, $34.8 million contract, with a reported signing bonus of $5 million up front. Gardener played one year with Denver, started two games, and never recorded a sack.

The off-season after Baltimore won a Super Bowl with Trent Dilfer at quarterback, the Ravens inked Grbac to a five-year, $30 million deal. They gave him $11 million guaranteed and he lasted just one year.

One of Dan Snyder’s first big deals as owner of the Redskins, Stubblefield snagged a six-year, $36 million deal with $8 million guaranteed from Washington after a breakout ’97 campaign with the 49ers. He played three years for the Redskins, battled injuries, and had just 7 sacks — 8 less than he had for San Francisco in ’97 — in Washington.

After an injury-plagued four seasons in Oakland, the Dolphins gave Grove a five-year, $29 million deal to be their starting center. He played in 12 games, got injured, and was cut the following off-season. So much for that.

After Kurt Warner retired and Matt Leinart was released, the Cardinals opted to ink Anderson to a two-year, $7.5 million deal in free agency. Undrafted rookie quarterback Max Hall seized the starting role from Anderson after just four games. Anderson was released after the season.

After a tumultuous end to a Colts career in which he never won a Super Bowl ring, the Canadian placekicker who was never shy to speak his mind signed a three-year, $4.5 million deal with the Cowboys. He played one year in Dallas and missed 5 of his 18 field goal attempts.
