Incredible moment as he finds out he is now a Hall of Famer. (via ) NFL (@NFL) Johnson was the architect behind the greatest three-year turnaround in NFL history. In 1989, he inherited a moribund franchise that would go 1-15 during his first season in Dallas. But that season, following his famous Herschel Walker trade, would lay down the foundation for what was to come. Johnson's Cowboys reached the mountaintop in 1992, dominating thein Super Bowl XXVII. The Cowboys would become the sixth team to win back-to-back Super Bowls the following year before Johnson stunned everyone by resigning that offseason. Johnson returned to coaching in 1996, leading the Akito Hirose Jersey to three postseason appearances before stepping away for good after the 1999 season.A national championship-winning coach during his five-year run at the University of Miami, Johnson's tenure with the Cowboys was off to a slow start in 1989 before he helped engineer one of the greatest trades in NFL history, a trade that spearheaded his Hall of Fame coaching career.In the midst of a 1-15 season, Johnson had traded their best player, running back Herschel Walker, a 1,500-yard back the previous season, to the in exchange for a bounty of future draft picks. While the Daniel Sedin Jersey trade was widely unpopular at the time, Johnson was confident that it was the right thing to do."One agent said it's the biggest trade he has ever seen in the NFL,"Johnson said during a pre s conference following the trade, "and one owner said it's a great train robbery. Whatever it is, we're happy with it."The Cowboys used the picks to help build what would become one of the best rosters in NFL history. In 1990, they used their first pick acquired from the trade to select Emmitt Smith, who would go onto become the NFL's all-time leading rusher. Over the following two drafts, the Cowboys would select future Pro Bowl defensive tackle Ru sell Maryland, perennial starting cornerback , and future three-time All-Pro safety Darren Woodson.Along with several other acquisitions, the Cowboys went from NFL doormats to NFL champions. In 1992, just three years after pulling off the greatest deadline deal in league history, Dallas won the Brock Boeser Jersey first of its three Super Bowl wins over a four-year span. Johnson will join several former players in Canton from his time in Dallas and Miami that include Smith, receiver Michael Irvin, lineman Larry Allen, quarterbacks Troy Aikman and Dan Marino, and pa s rushers Charles Haley and Jason Taylor.Cowher, while paying homage to the cameo role he shared with Johnson during the 1998 hit comedy "The Waterboy", congratulated Johnson on his selection on Sunday nigh.Congrats to on joining the ! I wonder if knew he had two future Hall of Famers in the stands watching Bobby Boucher in The Waterboy?
