Russell Wilson
This was one of the worst NFL trades of the past decade and it could ultimately end up being the worst. Wilson represent the Seahawks with pride as he won a Super Bowl. But things became stale in Seattle before they traded him to Denver. Some analysts thought that they should fire Pete Carroll instead of shifting their MVP contender quarterback (via SBNation).

But they traded him to the Broncos after Aaron Rodgers rejected Denver’s advances. Denver gave up two first-round picks, a pair of second-round picks, a fifth-round pick, and multiple players for the star. They expected to become immediate contenders but he played atrociously for them. Meanwhile, Carroll put his faith in Geno Smith who won the Comeback Player of the Year.
