I think last weeks reveal was more about presentation, then the actual engines. Granted they touched on passing and what not. But tackling has been greatly improved. It's not the huge jump we saw when gang tackles were introduced. But it's a lot better. Not as much bouncing off defenders. Defenders really wrap up guys now. I can't remember in any older Madden title seeing defenders actually wrap up runners legs. And as far as impact goes, it's been toned down, not as many whacky flipping through the air tackles that jsut look out of place. There are still big hard hits, and a defender dropping a shoulder will cause a runner to go flipping over them.
