"I want to continue my career wherever I have the opportunity to win a playoff game and get to the Super Bowl. That's where I want to be," Johnson said.
When asked if that described his situation in Cincinnati, Johnson said: "I'm not sure. I have no idea."
Johnson also said he wasn't sure if he wanted to return to the Bengals, saying he was "undecided." He said he hasn't spoken with anyone from the Bengals this offseason.
Johnson, who finished with a single-season franchise-record 1,440 receiving yards, has had six consecutive seasons with at least 1,000 receiving yards. He is under contract with the Bengals through 2011 after signing a $35.5 million extension in April 2006.
However, Johnson has been outspoken this offseason about his unhappiness with the situation in Cincinnati.
Coach Marvin Lewis has said repeatedly this offseason that the Bengals have no plans to trade Johnson. "There will be no trade of Chad Johnson. Repeat it again," he said in January.
Despite his franchise-record yardage total in 2007, Johnson said he wasn't happy with his performance.
"I consider it a bad year for me because I had some inconsistencies myself," he said.
"I just didn't play well. I didn't play well at all."
Johnson also acknowledged an incident did occur in the locker room during a 2006 playoff game but denied that he threw a punch at coach Lewis.
"There were no punches thrown. Anything of that nature I would have been released. I would have been cut right away," he said.
"Coach Lewis had to restrain me. That's as far as it went."
