All you had to do was go in Hailmary formation and either scramble and outrun the defense or act like it and then chuck it 60 yards downfield for a touchdown.
Another good strategy that worked for me in last years game (for a while) was playing as Baltimore and spying with Ed Reed while using the Dollar Fire Blitz defense on basically every snap. They were so agressive that if you didn't throw it within 2 seconds you would be sacked nearly everytime. Ocassionally you will get those smart opponents that will quick throw it to the Tight End for usually about an 8-15 yard gain everytime so It can work against your average to below average opponent but most times not against the "Good guys".
With Denver, I just let Champ Bailey do all the work, he gets atleast an interception and sometimes a touchdown each game. They made him almost godlike with that new Icon thingy. I put him as my kick/punt returner to and he has some made crazy skills.
The thing about alot of sports games is they lag soo much, so I've stopped playing madden and converted to Call of Duty 4
