Hi charter04!
Could be me being stupid but I swear I was in CFM in a preseason game and was able to tweak the CPU and PLAYER sliders on Saturday then Sunday my game flaked out a couple times and I noticed I could not change them.
You would know best though my friend!
ps
If your on XBOX One and your console goes into Standby mode do not expect to resume your game. I lost 2 games because of this last weekend...
