I honestly don't know. I've never tried my sliders with coach mode. I think they would potentially provide a decent base with some things needing some boosts to it. Like, I expect my USER QB Accuracy and Run Blocking values are going to be pretty low based off how I see the game is tuned in the videos and those are values that are fine lowered for a user controlled team, but may need to be boosted a little for coach mode.
Things like Pass Coverage and whatnot won't need as many adjustments potentially since I already play No Switch and those are areas that are more CPU player dependent anyways, so they'll already be tuned for CPU control if that makes any sense. Feels like I worded that terribly. Basically, the areas of the game the user has the least impact on I think will work for coach mode, but the other areas that are influenced more by user skill would probably need some adjustments for coach mode.
