I just got the game two days ago, and I have played online twice. The first game I won 31-21 playing with Philly against the Cowboys and the second game I lost 17-7 using Philly playing the Raiders.
I have played NCAA 10 a fair amount but I wanted to try my hand at Madden. I have been reading the offensive/defensive strategy threads and I am gonna try to implement some new things when I get back to my house. I definitely have a lot to improve on and I think there are useful posts and it seems that there are lots of informative and experienced players here.
