When I first got the 2005 game and knew so very little about how to play, I found some information that stated allowing the center to point out blocking assignments would help with running plays.
I had started a dynasty with San Jose State University ranked #108 in the nation and I needed all the help I could get. Waiting for the center to point seemed to help with all my weak running plays. It also ran the clock out on the other offenses, which was SO necessary, because my defense was so porous. Partly because of this, I was able to take SJSU to a 7 and 4 record when they should have been maybe 4-7 or 2-9. (The real SJSU football team went 2-9 in 2004.)
In the third year of the dynasty, with a ton of luck, and by keeping the ball away from their offense, I was able to eke out a watershed, upset, one touchdown victory over USC.
You have established through experimentation that the center point actually does work for pass blocking schemes! Congratulations and thank you.
