Yeah, player ratings can be a bit of a crutch because they're pretty high. Run the same play vs the same defense (same matchups) and you get a VERY consistent outcome each time. The lower slider settings reduce the certainty in getting a 'clean' interaction. As you know, sometimes a slight reduction in block duration, a surprisingly effective move, or a more off-target throw can completely change the dynamic of how a play plays-out. When you apply that nuance across all 22 players, a lot of fun things can begin to unwind.
Then you add in the dynamics from the coach adjustments and momentum and things can begin to really change a lot.
I've had an absolute blast (in spite of losing nearly every game, lol) since making the move to this setup. The variety has just been outstanding....finally seeing low scoring games mixed in with the others.
