I'm relatively new to football and madden. I've played since madden 08 and love to play madden 10 currently. But im still very knowledgeable. I have some questions like what does a 3-4 and a 4-3 Defense mean? is it 3 linemen 4 linebackers? cause thats what i currently believe it to be. and if so what are the advantages of them and are there other styles of defense?

-Thanks, Rayn
