Only a week after the NFL pulled the plug on its overseas developmental league, the Bears have terminated the contract of the veteran regarded as the top player in NFL Europa this spring, releasing much-traveled quarterback J.T. O'Sullivan. The move came only three weeks before the defending NFC champions are scheduled to report to training camp, and reflected O'Sullivan's status as a long shot to win a roster spot. Chicago currently has four other quarterbacks -- starter Rex Grossman, veteran backups Brian Griese and Kyle Orton, and undrafted free agent Chris Leak, who led the U. of Florida to a national title in 2006 -- on its depth chart.
