Bears wide receiver/kick returner Devin Hester doesn't think signing veteran Donovan McNabb would help the team. Caleb Hanie has struggled in place of Jay Cutler, who had thumb surgery recently. "It's going to be tough right now to pick up a quarterback that hasn't played in the Mike Martz offense," Hester told ESPN Radio. "This is a difficult offense to run, so as far as a quarterback who hasn't played in the offense, right now it's going to be a waste of time." Martz, Chicago's offensive coordinator, runs a complicated scheme, meaning McNabb would have to play a whole lot of catch-up to allow the Bears to work off the entirety of their playbook.
