Hi there, looking to get more competitive this season in my league and figure out how to set rules that can help me be more dominant offensively/in the passing game. Could I get some advice and tips on the types of rules I could set?

Here's a link to a basic game planning guide I wrote. It pretty much covers most of what I think is best and I don't want to type it all out again. https://usflwfl.myfootballnow.com/community/3/7400?page=1#45150

Mostly just optimize your passing plays for out breaking routes, have fast players with 80+ in key skills, and pay attention to where your QB is putting the ball and put your best players in those spots

After a couple-threeish years of play, I gave up on offensive rules.
Why?

The likely-hood of any specific play (this play on that down by this yardage) is incredibly slim. That led me to blanket offensive plays (By formation, by set, and eventually a dramatic minimalization of my offensive plays - see the above post) to effort trying to get at least some general results.

Which led to my offense being easily defensed against by blanket D rules by those that use rules in the first place.
Which led me to only using blanket D rules. :)

Always have D rules keyed towards formations that only use pass OR run plays EG: 5wr and other pass only sets; the 2.3.0).
Always use a 4 game data set.

From there, one would have to discuss the run/pass tab as well as how to use the 4 game data to determine sliders in Def rules vs any formation that uses both run and pass, yet has a significant preference towards one of them. I set my DEF tab R/P sliders at neutral. Player created rules always have first priority. I want my created rules to not have any opportunity for potential differentials.

That last paragraph is an entirely different topic worth discussing.

EDIT: additionally, all these things must also be considered within a place/time specific offensive rule. Offensive rules are like throwing darts at a grape. It's possible to hit the mark, but it's often fruitless. HA!

I encourage focusing on D "key" rules - those that focus on run only or pass only plays, if you are not doing so already, and to experiment with rules for your offense to get the results desired. The former is far easier of an approach when learning how to use rules, and will lead to a better understanding about how and when to use offensive rules.
2 cents deposited into the opinion bank, use my money well, hehe!

As a joke:
If you really want to pass a LOT, just be behind in the score.

I'm happy to share my OR/IR/SP/MP/LP offensive slider settings with you if you would like to have a base of what I found worked for me over multiple versions of MFN.
Also, do NOT use Long passes. The last, last, last (v4.3) "fix" broke long passes, and v4.6.2 (def play removals) nerfed ALL of the 2.2.1 double TE passes.

Some jokes are so truthful they hurt.
4 cents. Ha, Ha, ha!

You would think by now, we'd all know not to use long passes but I still see some teams use it when I scout opponents. Personally, it's been a long time since I even had a long pass play check marked.

For those that still don't know, DO NOT USE LONG PASS PLAYS.

Limit O plays that have a RB preference (see setherick's data somewhere).
To add to raider's info:
Ever since long passes were neutered, RBs tend to be the easy completion - regardless of where the rb is in the pass progression. Unless the GM limits the RB checkdown through pass play selection, the RB will become over targeted. (TE the rb then wr in targeting).

it's very hard to eliminate the TE from getting the most targets in v4.6. My experience has shown that the only way to increase WR targets (to achieve TE/WR/Rb or WR/TE/RB in total targets) is to limit pass plays that include a RB/FB as a target.

PS: the 2.3.0 is crapola ever since it's only pass play was neutered. Rightfully neutered in 4.4(b).
*ABuse the slot wr, never have a slot wr under 5'11.
*use an Oline at TE if that TE position does not go out for a pass in a formation or only running from eg 2.2.1 or 1.2.2 (also those pass plays in those formations have been neutered).
