Yeah the AI deliberately makes wrong decisions in Madden, just so the video ref can be used. The video ref wouldn't fix physics engine errors or anything like that, the game would decide if a close call was a try or not then play through its cutscene. I'd rather have it black or white, if you dive over the line in a tackle, it should always be a try or always be held up, not up to some 50/50 guesswork. I'd hate to know that my dive for the corner late in the game for the win would come down to a 50/50 chance based on the AI because of the video ref, I want either a try or no try, no middle ground in the physics.
Seriously, what good would the video ref do other than slow the game down and frustrate you? If they implement it well, I'll deal with it, but really, I see no need for it, it'd just be bells and whistles the game doesn't need, especially when so many other parts of the game need work.
