The O-line and Blocking

March 08, 2011 at 03:53PM View BBCode

OK, now that you are re-writing the way that pressure works and stuff, I want to make sure that I understand how the O-line works.

Right now I am rewriting how pass rushing is handled; I am going to an individual matchup approach for sacks. This will hopefully help bring sack numbers in line with reality, make blitzes more effective, and allow me a lot more flexibility in how blitzes and pass rushes are handled, meaning (among other things) I'll be able to introduce the 3-4 formation with these changes in place.


What exactly is that going to mean?

Does it mean that you will look at the O-lineman's pass blocking vs. the Defender's pass defense rating and modify the numbers based on strength, agility, execution, etc. in order to get some one-on-one blocking situations?

Because previously, when you were looking at the O-line as a unit, the pass blocking didn't work very well if you had even just 1 weak link and there were oodles of sacks and pressures all over the place but the passing numbers were still very high.

I guess I'm just curious what the new blocking engine is going to be working like so that I know how to rank my O-line positions in the draft.

I'm still hashing out the details as I write it, but here's where things are so far. Before, there was a specific overall "sack rate" that was applied on each play, and that rate was divided up among the pass rushers. The only individual matchup was RDE vs. LDT for the blindside calculations. The system was hard-coded to pit 4 on 4, which limited the formations and left out the option of using the TE as a pass blocker rather than a receiver.

Now, each pass rusher has his chances of delivering the hit calculated individually, and that information is store in his player object rather than in a hardcoded table, so I can theroretically assign any defensive player to pass rush now. This opens up a lot of flexibility in what I can do with the defense.

As of this moment, I am only testing that part of it, so the O-line is still using the same calculations, except I have put a floor on it, as looking in the logs I could see how a tired O-line just falls apart, and the new more detailed pass rush tears through it like tissue paper. So I've put a floor in the calculations for it so it can hold up as I get the first part of it working properly, then I can do the offensive side in the same way, allowing you to assign who is on pass blocking duty on both the line and in the backfield, and rather than have it hard-coded by role, have it match up against the defense by physical location on the field (which opens me up to being able to do traps and stunts properly).

Really, it's all what I'd intended from the beginning, but at some point I had convinced myself I was over-engineering it and just decided to treat the O-line and D-line as a unit. The problem now is that I no longer have the luxury of time; every day that goes by without fixes getting in, these abusive offenses are racking up yards and turning people off of the game.
