The Dallas Cowboys are taking a chance on another suspended defensive end, signing Aldon Smith to a contract while his playing status in the NFL is uncertain. The Cowboys now have two suspended pass rushers under contract in Smith and Randy Gregory. The 30-year-old Smith had several legal issues as a player with San Francisco and Oakland. He was first suspended with the 49ers in 2014 before receiving a one-year ban in November 2015 with the Raiders. He had 19 1/2 sacks in his second NFL season and was an All-Pro while helping San Francisco reach the Super Bowl.
