NFL: Five Biggest Blockbuster Trades of All-Time

4. Seattle Seahawks trade for New York Jets' safety, Jamal Adams

Wild Card Round - Los Angeles Rams v Seattle Seahawks

The New York Jets surrendered Jamal Adams to the Seahawks in one of the biggest NFL trades last season. The Seahawks received New York's All-Pro safety and a third-round (2021 pick) in return for two first-round draft picks (2021 and 2022), a third-round draft pick (2021), and safety, Bradley McDougald.

His 2020 NFL season may have been a stop-start affair due to injury, but nobody is questioning the ability of Jamal Adams at safety; he is outrageously good at all aspects of the position. What remains to be seen though is exactly which team (the Seahawks or the Jets) got the best deal in the trade.

Adams may have committed his long-term future to the Seahawks, but the Jets have two first-round picks coming up in 2021 so we won't have to wait much longer to find out.

3. The Oakland Raiders trade Khalil Mack to Chicago Bears (2018)

Chicago Bears v Los Angeles Rams

In a seven-year career, Khalil Mack has consistently been one of the best defensive players in the NFL. As such, his 2018 trade was a blockbuster of the highest order.

Of course, Mack now operates at Soldier field for the Chicago Bears, but things could have been very different: if Raiders head coach Jon Gruden had found a few extra dollars in the Oakland war chest during the 2018 offseason, perhaps Mack would still be dishing out his unique brand of punishment in the heat of Las Vegas, Nevada.

It wasn't to be...

The tight-fisted Raiders traded Khalil Mack, along with second- and conditional fifth-round picks in the 2020 NFL Draft, to the Bears in exchange for first and sixth-round picks in 2019 and first and third-round picks in the 2020 NFL Draft. It was a trade that saw Mack become the highest-paid defensive player in the history of the NFL and he showcased just why in his debut season with the Bears.

The Raiders used that 2019 pick to acquire Joshua Jacobs in the NFL draft, the bruising running back who has been a revelation since he arrived in Las Vegas. Khalil Mack made the Pro Bowl in each of his first two seasons in Chicago but did endure a noticeable dip in form in 2020.

Bears fans needn't worry just yet: at just 29-years-of-age, it's more likely that Mack will rediscover his dominant best form than not.
