Everything is situational but you might be better than you think you are
as my last season ended 9-7 as the texans and I won the first 7 of those games lol so I thought my sliders were screwed but then the tides turned after Brian Cushing got injured, so just keep on playing. I think these sliders are near perfect for what I want from the game.
If you want CPU to have an advantage, then I'd say to up all CPU sliders by 5 except pass block, unless you like suction blocks
