Bears wide receiver Johnny Knox says he has no plans to request a trade despite his recent demotion. Knox has been demoted in favor of newcomer Roy Williams. "I'm a Bear, and I want to stay a Bear for life," Knox said. Knox wasn't surprised about such speculation after Williams replaced him as the "X" receiver in offensive coordinator Mike Martz's scheme. "I could see where people were coming from, but it was basically people trying to stir something up," Knox said.
