IRVING, Texas -- Former Arizona Cardinals running back Ryan Williams was impressive enough in his workout Saturday morning at Valley Ranch that the Dallas Cowboys are considering signing him, two sources said.

“I’m hoping ‘great’ means I can be here,” Williams said of the feedback he got from Cowboys front office personnel and coaches after his workout. “If not, then I’ll keep moving forward, but I’m really hoping it’s here.”

The Cowboys have 90 players on their roster, so they would have to cut somebody to make room for Williams, the 38th overall pick in the 2011 draft who was released by the Cardinals this week. His tenure in Arizona was marred by injuries, limiting him to five games in three seasons.

He missed his entire rookie season after rupturing the patella tendon in his right knee during a preseason game, causing his knee cap to slide into his thigh. He gained 164 yards on 58 carries in 2012 before a shoulder injury ended his season. Williams did not play last season, rehabbing his knee, which he says is finally back to 100 percent.

“I’ve worked my tail off to get to this point,” Williams said. “It was a rocky road, but I got it done. Regardless of how anybody sees my career going, it was beneficial for me not to play last year and the other year I got hurt with my shoulder. It just gives my knee more time. This isn’t an easy injury to come back from at all. It worked for me.”

Williams realized he’ll be remembered as a bust in Arizona. He’s determined to realize his potential at his next NFL stop.

“Every ounce of blood in my body, man, every inch of skin,” Williams said. “I want to come in this game and leave it with a legacy. Not a legacy of being hurt – a legacy of being a guy you can talk about for years to come as far as being one of your favorite running backs.”
