according to pro football focus, the cardinals ol was 17th in the league this year. That is pretty much the definition of an average group. They go up against a panthers front that may not have necessarily earned its fierce reputation.
The panthers have played 17 games so far. In those games, they've faced 9 teams with an ol ranked higher than the cardinals:
cowboys (1): without romo to worry about, panthers stacked the box, got 3 sacks and only allowed 31 rush yards.
saints (3): in 2 meetings with a familiar divisions opponent, panthers got 3 total sacks and surrendered 140 total rushing yards.
falcons (4): in their embarrassing first meeting, the falcons gave up 2 sacks and rushed for 77. In handing the panthers their only loss, they gave up 5 sacks and only rushed for 54 yards.
packers (7): 5 sacks and 71 rushing yards against a battered ol.
redskins (11): 5 sacks and 14 rushing yards allowed.
eagles (12): 5 sacks, but 117 rushing yards allowed.
colts (15): this ol was infamous for getting luck killed, but only gave up 2 sacks against the panthers while rushing for 136 yards.
texans (18): 1 sack and 61 yards
jaguars (19): 5 sacks and 96 yards
giants (t-20): only team not to surrender a sack. Also racked up 161 rushing yards
buccaneers (23): first meeting - 2 sacks and 141 rush yards allowed. Second meeting - 5 sacks and 78 rush yards allowed.
titans (29): 1 sack and 64 rush yards allowed
seahawks (30): seahawks gave up 9 sacks over the course of two games, while rushing for 115 yards and 78 yards, respectively.
It seems to me that there is no rhyme or reason to when their d dominates an opposing ol. They owned good squads. They were held in check against inferior squads. The team that beat them had a much worse game in victory than in defeat!
The one thing that does stand out to me is the lack of elite qb's they have faced this year to keep them honest. (brees x2, rodgers, eli manning, russell wilson x2) are the only qb's that could expect to keep them honest.
Furthermore, there is no definitive split in performance for the panthers d when they play at home or away. In other words, crowd noise doesn't seem to assist them to play better than when they are playing on the road.
In all, the panthers average 2.9 sacks per game and allow 84.3 rushing yards. If they play to this average and carson doesn't throw any int's, i'll take it. I think the cardinals could probably win in that situation.
