From Tom Pelissero's tape review, about the Green Bay Packers new Psycho defense (1 lineman, 5 LBs, 5 DBs):
In all, DC Dom Capers ran "psycho" six times, all on third down, and the Bears converted only one — a 19-yard strike from Cutler to WR Devin Aromashodu a tick before a trio including Jenkins got home.
DE Cullen Jenkins was the one remaining lineman, and he was the most effective player in the Psycho package. But, as Football Outsiders pointed out, QB Jay Cutler was usually in a bind on 3rd down because of their struggles on 1st and 2nd down:
As a sign of how effective Matt Forte and the Bears' offensive line were on Sunday, here's the number of yards Cutler had to pick up to convert on third down, listed chronologically: 21, 8, 18, 9, 12, 1, 5, 10, 22, 11. That's an average of 11.7 yards to go; the average quarterback needs to gain an average of 7.7 yards on third down to get a new set to work with.
Overall the Bears were 5 of 13 on 3rd down, so they were a respectable 4 of 7 on 3rd down when the Packers were not in the Psycho package. That might be an indication that the Packers are not good on 3rd down in a base package, or that they only used the Psycho package on 3rd and very long. The Packers' opponents have only converted 34.7% of their 3rd down chances this season, which is currently 6th best in the NFL.
For the season, the Steelers are about league average on 3rd down, converting 38.1% of the time, but 3rd down was a disaster for them last week against the Browns. Again, from Football Outsiders:
How do you score six points in 60 minutes against the Browns? Drop back 11 times on third down and convert exactly one of them. Roethlisberger even failed to complete a pass on the first nine of those attempts, taking five sacks and throwing four incompletions.
I thought that maybe the Steelers were putting themselves into a lot of 3rd and long situations, but in the first half against against the Browns, the Steelers failed to convert on 3rd and 1, 3, 1, 7, 5, and 19. I didn't even look at the second half because the first half showed that they had a lot of 3rd and short opportunities on which they failed to pick up a 1st down.
John Harris of the Tribune-Review points out that the Steelers were able to convert on 3rd down when they ran the ball, but on their current 5 game losing streak, they have only converted on 3rd down between 20% to 38% of the time. So that's converting only 28% of their 3rd down chances over their last 5 games.
There seems to be a lot going wrong for the Steelers on offense at the moment.
