Lowering fumble on All Madden turns down the beast mode. And there's not that many fumbles. I've been testing at 22 fumble, 0 run block, and 11 tackle. for human and cpu. it feels close but its not quite there. 0 fumble turns the rbs into Tecmo Bo. With a much higher tackle slider, 0 fumble could be something special as well. but i prefer the low tackle. wish i could figure it out at 0 but was willing to bend to 11.
