I'm not sure bringing down the fatigue to default would be the correct way to do it tough, as it would affect the D-Line as much as the O-Line. Plus, it would screw up all the other positions too, which are fine with Aaron's sub set.
I was thinking more about bumping sub in/out for the O-Line...maybe not to the extent of where the DL is (usually 50/55) but probably a lot higher than 0/3, which I'm at right now.
I'm just not sure if I get how fatigue and subs work correctly. The way I understand it, a DE/DT would get subbed once he goes under 50. But the OL never gets subbed. So I wonder if on long drives, and possibly near the end of the game, the OL isn't just too exhausted to block correctly.
But I'm really not sure...it's not even a theory at this point, I was just curious to see if anyone had tried it.
