Free-agent WR Terrell Owens (Bills) is worried NFL teams are swayed by the perception he is a troublemaker - a perception he believes he disproved with his agreeable behavior while with the Buffalo Bills last season, according to Rachel Cohen, of The Associated Press. 'There were a number of times where prior I probably would have reacted, said something I wasn't supposed to say,' Owens said. 'I really had some restraint, very patient.'
