I don't. I just want to put players on the field and see how they perform. And I'm glad that Madden has a little bit of realism in this regard cause some players play better than you'd expect them to. This should be taken further.
Like I had my #1 and #2 WR and the #2 was way better even though he was rated lower. I didn't check his ratings of course but he was second on the depth chart so that gave me some idea of his skills.
