I think there are a few factors with the 4th down issue. As others have mentioned, I also believe that NFL coaches tend to be overly conservative due to the culture of fans and the media...(but that conversation is probably a thread of its own). But the other issue is that video games football games (just speaking generally here...not M12 specific) tend to be more offensive that their real life counterpart. So from a pure percentages standpoint, it can be a correct strategic decision. Not only are my chances of converting higher than they should be, but the chances of stopping my opponent is also small....so I don't really get much out of the punt. Again, I am speaking in general terms here.....I have sliders slanted to the defense, so punting tends to be a good choice for me.
