Since the talk has died down in here, I thought I'd give a brief explanation of what the Rams do on defense. I think everyone is familiar with Gregg Williams and his love of blitzing. He also has a lot of pre-snap movement and disguise when it comes to his defense. When it comes to coverage, we play a bend but don't break system.
Our guys typically play off with a decent sized cushion to force teams to throw underneath our coverage. The logic is if we do our job and tackle, we force teams to go on a long sustained drive where one mistake (like a sack, TFL, fumble, INT) will kill the drive. It can be very effective when we're stopping the run. When teams are gashing us for 5-8 yards on first and second down, it can also be very ineffective. So the one of the biggest keys for the Rams defense will be stopping the run. When our defense forces you into 2nd and long or 3rd and long, they tend to feast. Because the opposing QB has to pick their poison.
They can either throw underneath the coverage and hope their WR/HB/TE can break tackles/make people miss or they can try to wait for a longer developing route to open up down the field giving our DL and the blitzers time to get to the passer.
Obviously, that makes tackling effectively after the offensive player catches it a very key priority. Ben will likely complete a very high percentage of his passes today unless you guys fall behind early and are forced to push the ball down the field.
But completion% won't matter much in the end. If the Rams defense is effective (i.e. they stop the run and tackle well), Ben will be able to complete 70% to 75% of his passes but only for 6-7 YPA and Pittsburgh will struggle to score. If they don't stop the run or don't tackle well, y'all will probably move the ball up and down the field all game long.
The Rams defense can be a bit jekyll and hyde. They have the potential to put the clamps on just about anyone but they also have the potential to get burned. Our guys are still somewhat young and make mistakes (especially our DBs).
Oddly enough, with all the blitzing, you'd think that Gregg Williams's scheme would be "aggressive" but it's actually a paradox. It's an aggressive conservative scheme. Aggressive in the sense that he's constantly bringing pressure and attacking the LOS but conservative in the sense that the Rams still manage to play it safe with a bend but don't break defense that forces teams to sustain drives.
