The best trade in NFL history in my eyes was when the Dallas Cowboys traded Herschel Walker to the Minnesota Vikings. This trade was epic.
For the Cowboys, of course.
In 1989, at the peak of Walker's NFL career, the Cowboys sent Herschel Walker to the Vikings for five players and six draft picks.
The players were LB Jesse Solomon, DB Isiac Holt, RB Darrin Nelson, LB David Howard, and DE Alex Stewart.
The picks turned into players such as Emmitt Smith, Russell Maryland, Kevin Smith, and Darren Woodson.
Emmitt Smith is one of the greatest, if not the best running back in NFL history. He is the all-time leading rusher with 18,355 yards. His 175 total touchdowns rank him second all-time behind Jerry Rice (207.)
He is one of four players in NFL history to eclipse 21,000 yards. He is also one of the two non-kickers to score over 1,000 points in his career.
Emmitt holds many other records. He is also in the Dallas Cowboys Ring of Honor, and will soon be in the Hall of Fame.
Darren Woodson was selected to five pro bowls, and was named all-pro four times. He is the Cowboys' all-time leading tackler with 1,350 career tackles.
Walker played two years for the Vikings and never surpassed 1,000 rushing yards. He went on to play for the Eagles and then the Giants before being re-acquired by the Cowboys.
In my opinion that is one of the best trades in NFL history, and one that built the Cowboys' dynasty of the 90s.
