I must confess that the thought of Rodgers having surgery on his shoulder bothers me. As someone who has prior experience with rotator-cuff injuries, I know how long they can linger. Most people I have known who had shoulder surgery took years to return to full strength -- if they ever did.
On the other hand, Rodgers has played through the injury and performed admirably, so perhaps there's no grounds for major concern.
Still, there's always the possibility of the surgeon's scalpel slipping . . .
