"Contrary to an Internet report Tuesday, the Bears are not shopping Greg Olsen. Citing friends of Olsen, nbcchicago.com reported that the Bears tight end was not happy about the hire of new offensive coordinator Mike Martz and that he ''quietly sent his agent Drew Rosenhaus into 'trade request' mode.'' That's not the case, a league source said. The Bears are not actively trying to trade Olsen, although that could change if another club makes an overwhelming offer."
