Yea you can hold bad players to under 20 points. But as soon as someone learns how to pass in this game, it opens up the flood gates. Cover 3 or even 4 aren't viable defenses. You can just run seam routes all day against it, just max pass inside or out for an easy 15 yard pickup. The defensive AI never reacts. It's like they can't adapt to passes that are modified in any way.
Just played another game online right after I made this post. Went 11-18 for 363 yards and 4 TDs. Doing nothing but abusing seam routes really.
And comebacks aren't beat by press I tried that. And deep outs again this is coming from someone who understand to throw before the WR makes his cut are uncoverable in man coverage. I was burning Deion in practice with it over and over.
I'm sorry to say, but the defense at least in online ranked matches is god awful. Maybe it's different on all madden, but I don't play offline much.
