So now, even with Walton having missed most of a season and then being cut by the team that drafted him, the Redskins still wanted to take a look.
They claimed him off waivers Wednesday. Shanahan called this a move for the future, but Walton is an unrestricted free agent after the season. Still, it gives the Redskins a chance to see him up close for a week or so.
Walton played with Redskins quarterback Robert Griffin III at Baylor.
"[Griffin] knows what type of character he has and what type of guy he is," Shanahan said. "You always look into somebody's background and Robert gave him the highest recommendation as a person. But we'll go back and look at the film and we liked what we saw, not only in college but at Denver as well."
Walton suffered a severe ankle injury last season that caused him to start training camp on the physically unable to perform list.
"You always got the question mark with the medical, but we'll see that in time," Shanahan said.
