My guess is that once I start digging into this stuff I'll start to save some GPs that make the process quicker and easier. I'll be honest and say I still don't have a great sense for all of the interlocking FOF7 effects of formations, pass distances, expectation percentages, etc. The new game is unfamiliar, but I don't want to pretend that my comfortable semi-ignorance after years of numbers in boxes actually offered me more control. My gut is it'll still largely come down to snagging a good QB and putting some other talent around them. Trying to push as many of the other cohesion/gp/etc levers in the right direction are going to help you sustain and go from good to great, but I still think the big picture stuff is the thrust of the game.
All caveated by the fact that I don't really know what the hell I'm talking about yet...
