The Cubs paid a then-record $33.3 million for a pitcher who missed most of the season due to injuries. Sosa posted a 6.59 ERA in limited appearances, making this one of the most expensive pitching errors in MLB history.
Guaranteed $22 million for a 43-year-old hitter who appeared in only 97 games and struggled significantly at the plate. The deal is widely considered a poor allocation of resources given his declining performance levels.
The most infamous NFL free agent signing of the 2000s, paying $37 million over four years with $20 million guaranteed. Feeley played poorly for two seasons, leading to the Eagles drafting Donovan McNabb's replacement and eventually releasing Feeley.
Signed for $36 million guaranteed, Cutler averaged 1.5 wins per season over his tenure. The contract dragged on with full no-trade protection, making it a massive cap hit for a team that struggled to find consistency.
Although initially successful, Hader's performance declined sharply in his final year, prompting the team to avoid paying the final guaranteed year. The structure of the deal allowed him to test free agency after a subpar season.
Often cited alongside Eli Manning for draft value but distinct for his contract, Leaf signed a massive rookie deal that yielded only one winning season. His on-field ineptitude and off-field issues made him a symbol of draft busts.
Signed to a five-year, $40 million deal, Ward played just one season due to injuries. The Buccaneers had to buy out the remainder of his contract, resulting in nearly $30 million in dead money against the cap.
Manning had led the team to two Super Bowls, but his 2013 extension guaranteed $100 million made the final years disproportionately expensive for declining production. Critics argue the salary cap impact hindered roster construction significantly.
Peterson agreed to a $78 million guarantee but ruptured his ACL just weeks later, missing the entire season. The deal remains one of the most lopsided in NFL history, as he provided zero value for the guaranteed money.
The Mets invested heavily in a veteran outfielder who suffered a career-threatening knee injury in his first season. Although he returned briefly, the long-term financial commitment outweighed his limited impact on playoff success.
Beckenbauer's move brought massive commercial success but did not translate to on-field dominance in MLS. The salary structure, including guaranteed portions, was considered high relative to the league's competitive landscape.
After winning MVP, Noah signed a five-year, $110 million deal. However, subsequent injuries and mediocrity meant he delivered minimal basketball value for the final three years of the contract.
Selected third overall, Richardson signed a massive rookie contract but failed to establish himself as a starter. His brief, inefficient tenure and subsequent release made him a prime example of high draft pick disappointment.
While Thompson is a great player, his return-to-form struggles after ACL and Achilles injuries have led to debates about the value of his supermax deal. The guaranteed money remains high despite his absence from play for extended periods.
Brees signed a huge deal while aging, and while he played well, the contract's structure heavily impacted the Saints' ability to retain other key players. The final years saw diminished returns relative to the cap hit.
The largest contract in sports history at the time, A-Rod's production declined significantly in the later years due to injuries and suspensions. The guaranteed money far exceeded his on-field contribution in his final seasons.
Goff struggled immensely in his second year, leading to his trade. The Rams took on dead money and cap space, making the initial extension a significant misstep before his subsequent redemption with the Lions.
Ayton was expected to be a cornerstone but failed to develop into a star player. His contract became a burden as he played below his max status, leading to calls for him to be traded or restructured.
C Cousins played well initially but his contract ballooned due to the franchise tag and subsequent deals, creating significant cap issues. His eventual departure to the Redskins highlighted the unsustainable nature of the deal for Minnesota.
The first overall pick signed a massive rookie scale contract but was a complete bust in the NBA. His failure to contribute meaningfully makes him one of the most expensive draft picks in professional sports history.
