4. Panthers pounding the rock: Carolina ranks 24th in the NFL in rushing offense, but Ravens coach John Harbaugh said the Panthers "run the ball as well as anybody in the league." He must have been looking at tape from last season. The Panthers average 3.6 yards per carry, starter DeAngelo Williams is out for the season and his primary backup, Jonathan Stewart, has been mostly ineffective when healthy. Mike Goodson, who ran for 100 yards last week, could get the start. But if the Ravens can build an early lead, they won't have to worry much about the Panthers' fourth-stringer coming Sunday.
