Im not the most insane coach but I went 28-2 last season so now I have a big head.

It sounds like you're trying to recreate the wheel my guy. You jumped right in to own a team an now you're trying to figure everything out on your own. I mean sure it's possible to just figure things out on your own (PH33P and Kvothke come to mind) but it would be a lot easier to just jump on a decent team and see how they do things. And I do mean
a lot easier. The vast majority of my offensive coaching knowledge comes from the time I spent on "John Gruden's Nightmare" with Agerm, Bruce, DallasCowboy and jhiggseiu14. Literally all my defensive knowledge for my current team comes from just idlily observing things as Gliwice Lions defensive coordinator. My current defensive scheme is just a cheap imitation of the Blood Sweat and Beers Hybrid defense. A team I also closely observe as the Assistant OC.
My S* DT builds was designed by Raid (whether he knows it or not lol). The rest of my D-line was designed by AltBruce. My CB, LB, and Safety builds were directly stolen from BSB (Sorry Leos). My HB build was given to me by Ghanima but even then
he got it from PH33P. My QB (Ozymandias "made in china") is quite literally just the Chinese knockoff of Gliwice Lions QB (Ozymandias king of kings). The only builds I actually sat down and designed on my team are the WRs and TEs.
I only have 3 players I made for my current team, 2 of which are free. Everyone else came from all the agents I had networked with the season before. I don't use GLB scout either, I just sit down and scout teams with a pen and paper. You really don't need to spend boatloads of money to be successful in the game. You just need to have a general idea of how to plan, put together, and run a team. That's hard to do unless you've been a part of the process before hand. I recommend you join teams, see what makes them successful, and try and recreate that with your own teams via putting your own twist on it. I also recommend you network with other agents in the future as opposed to creating all the players yourself.
It's really easy to shut out CPU teams if you know how to do it. Make two outside blitzing LBs and spam blitzes. Make CIT TEs and spam them on offense. You'll win. Hell, you'll beat most people if you do that. I mean just look at our last game playing a CPU a tier above us
