Williams, a second-string cornerback and the nickel back for the Falcons, hopes to erase any talk about his character this season.
It's a matter of "making 'SportsCenter' in a good way -- not having my name flashed on the bottom for nothing that I shouldn't be doing, whether it be a ticket, drunk in public, things of that sort," he said. "Try to stay out of the news. If I go out and perform to my ability, I can make 'SportsCenter' and I will make a name for myself.
"All I can do is ... keep my nose clean."
Williams is not only concerned with doing well off the field. He is still trying to prove himself on the field.
"Some days I have a good practice, and some days I might think it's good but the coaching staff might find some little things," he said. "I'm just getting adjusted to the speed and the endurance. ... The difference between college and the pros is you've got to perform at a high level every play. I'm trying to step my game up."
Williams said he is a little tired. The long preseason seems to be taking its toll on him.
"He's kind of at a standstill. I think he hit the wall a little bit," Falcons coach Jim Mora said. "He's got very good talent, but right now we're not seeing the consistency nor the physical play that we want to see out of him. I don't think it's unnatural ... for this to happen at this point with a lot of these rookies.
"We really like him a lot. I want to see him climb over this wall."
Williams did not get rave reviews from his coaches in a film session Monday for his play in a 20-6 exhibition win over Tennessee last Saturday.
"I felt good out there in the Tennessee game. I was out there in my swagger," he said. "I was comfortable, not nervous, not really worried about a player beating me. I thought I had a good game. We came into film today and the way the coaches made it seem to me, my performance wasn't that great. I guess when I think I'm doing good, it still might not be enough. But I can take criticism."
Williams feels like a target in exhibition games.
"A lot of players are going to come at you," he said. "They want to show you up, being one of the top defensive backs coming into the NFL this year. The receivers, they figure I'm one of the top rookies, one of the top corners, so they want to beat me even more."
Mora said Williams is working hard and has a "fantastic attitude" but needs to improve his fundamentals, such as footwork and hand placement.
