The Bears are offering up tight end Greg Olsen in a trade, according to agent Drew Rosenhaus. Rosenhaus sent a mass email to the league's general managers and personnel people on Wednesday night announcing the Bears were making Olsen available for trade. "The Bears have granted me permission to seek a trade for Greg Olsen," Rosenhaus wrote. "Please let me know if interested. Sounds like the Bears will be very reasonable on the compensation in return for Greg." But 11 minutes later, Rosenhaus sent another mass email to the same recipients, asking them to ignore his previous message. "Please disregard my previous email regarding Greg Olsen," the one-sentence email said.
