10. Ben Roethlisberger, Steelers: Roethlisberger is a proven big-game quarterback with only one losing season in his entire 12-year career. So why isn't he higher on this list? His 403 sacks absorbed are 152 more than any other quarterback over the past dozen years. Can we be confident that his body will hold up to the pounding for 16 games in each of the next five years?
