Yeah, that's a bit much. That's one thing that always gets me about Madden. Their superstars are a bit TOO super!
But as for whoever wrote about Green's strength in comparison to K.G.B's, I don't think "all strength ratings are created equal." What I mean is for a running back Green's strength is a 76. For a Linebacker, K.G.B's strength is a 75. They are compared with others at their positions, not overall.
