Anticipating that new Bears quarterback Jay Cutler will need more targets than converted cornerback Devin Hester and undersized journeyman Rashied Davisthe only receivers on their squad who have ever caught an NFL passthe Chicago Bears signed a tire swing to their roster Tuesday. 'We are expecting great things from this tire swing once the tire and Cutler get some practice time and develop some chemistry,' receivers coach Darryl Drake said of the six-year-old Goodyear all-season radial suspended from a tree branch by a 7-foot length of rope. 'This could easily be the best quarterback-receiver duo in recent Bears history.' Analysts say that, while the move is somewhat unorthodox, Chicago was prudent in passing on veteran free agents Amani Toomer and Joe Jurevicius in favor of offering the tire swing a 3-year, $2.4 million contract.
