Asked about his possible future with the club, Williams said, "Who knows."
"I feel like I made plays when the opportunity came," he added. "Of course, everybody's going to bring up the negatives, which is fine. But for the most part I made enough plays and I'll be happy to [re-]sign [with the Bears]. But if not, I'll continue on elsewhere."
Williams played perhaps his best game as a Chicago Bear in Sunday's loss to the Green Bay Packers, producing season highs in receptions (6) and yardage (81), and currently ranks third on the team with 33 catches for 447 yards and a touchdown.
Williams said he still "love[s] playing this game," and that the status of offensive coordinator Mike Martz has no bearing on his desire to want to return to the Bears. Martz is currently in the final year of his contract, and there are questions as to whether the team plans to bring him back for 2012.
"I'm looking for a team to go to the playoffs and go to the Super Bowl, and I don't think there's another team [close to that] than the Chicago Bears in my honest opinion," Williams said.
At the same time, Williams expects several roster changes and realizes the team might decide to move on without him. But that won't stop him from putting forth a strong effort in Sunday's season finale at Minnesota, despite the team having nothing to play for.
"It's being a professional," Williams explained. "It's tough to be in this situation, but luckily for us, it's only been one week. A lot of teams have been at this thing for 10, 11 weeks now, knowing they're playing for nothing. We're some fighters and we'll keep fighting. We want to try and end this year and start a new one off with a win."
