In 2014, the Dallas Cowboys made franchise-legend DeMarcus Ware a salary-cap casualty. The Cowboys deemed that the $7.4 million they could save by cutting Ware was worth more than his potential contributions moving forward.
Ware promptly signed with the Denver Broncos, where he went on to record 21.5 sacks in three seasons while becoming a Super Bowl champion in 2015. The Cowboys struggled to find anyone who could replace Ware, failing to produce a player with a double-digit sack season until DeMarcus Lawrence in 2017.
One team's trash can certainly become another team's treasure.
The Cowboys likely won't find or sign anyone with the caliber of Ware, but that doesn't mean that they can't find their own treasure while sifting through the rest of the NFL's trash.
