I know that the Special Teams plays are implemented very rudimental and that is known by the Developers and will change in the future. But I want to suggest one quick fix.

As I watch my games I see, that they are mostly won by one or two big (+50 yards) plays. This is because you always start from the near the 25 yard line and most of the plays are crap for an average of zero yards (either running plays or incompletions). If you would implement an average punt distance of the line of scrimmage + lets say 40 yards (or whatever is reasonable as Net Punt Yards). Then you would get some kind of "Game of field position", which is one of the most important aspects of a real football game. Especially for close games.
