Isn't amazing physics the first step in great fundamentals? If the players react the way they are supposed to when they are blocked/tackled/bumped, then they've created a great foundation. Add that to the fact they can make fumbles/injuries caused from actual physics and not just dice rolls as well.
This game has shown some flaws, but I just don't understand how football gamers on football sites can look at this and say "meh, I can deal with the football games on the market already, I don't need this one with amazing physics."
