David Irving is grateful for the Kansas City Chiefs. If not for the franchise the Cowboys will face Sunday at AT&T Stadium, Dallas' starting defensive tackle doubts he'd be in the NFL. "I look back all the time," Irving said. "It's crazy how it turned out. It's changed my life." After Irving wasn't selected in the 2015 NFL draft, Kansas City was the only team that called. He went through training camp with the Chiefs but was waived before the season opener and signed to their practice squad. A day after Irving purchased furniture for his new apartment, the Cowboys signed him to their active roster. "Broke the lease, left the furniture, just had to go," Irving said. "It was a crazy experience." Two years later and he's one of Dallas' most valuable defenders.
