They are very necessary.
I tested the edit theory out last night.
I edited them the first and 3rd games I played in my Saints season, and didn't edited them in games 2 and 4.
Wow what a difference.
In games 1 and 3 the cpu rb's ave 4.8 ypc in games 2 and 4 2.2 ypc.
A&S as usual great job with this set.
My only issues right now are punting (what a mess) and HUM CPU ACC.
I am completing too many passes.
