I was just simming a game and watching, and one team got up big 30-3 by the end of the first half, and the playcalling logic thereafter did not at all resemble a realistic set of results.
1) The team behind 30-3, but still with a whole half of football, kicked a field goal instead of going for it on 4th and 3 from the 3 yard line.
2) The team down 30-3 was still running the ball
3) Too many runs on 3rd and long in general
4) Not sure but I believe no onsides kicks were attempted
