Williams had 16 catches for 219 yards in 2010 after being a third-round draft choice out of Southern Cal.
Williams told The Tennessean that seeing so little time on the field as a rookie was a learning experience, but allowed him to figure out the speed of the game and how to prepare every week.
"I know what it is all about now," Williams said. "Your rookie year, you are playing with grown men and you are fresh out of college, so it is different. But now I have a year under my belt and I know how to prepare for things, and just knowing how to prepare is probably the biggest thing. If you can get over that hump, you can make it.
Williams arrived in Nashville recently to work out with teammates. He's currently working on improving his stability and on ways to avoid injuries moving forward.
"I feel I'm ready. We could play tomorrow," he said.
Quarterback Rusty Smith, who has been a regular at team workouts, said Williams is committed. As rookies last season, Smith and Williams regularly worked out together focusing on routes.
"Damian is a great athlete," Smith said. "He's a hard worker; you know he's going to put the work in.
"I have no doubt he's going to be a great player for us. He's only going to get better and better, and I know the coaches like him. Personally, I love the guy."
