I've always found the "such and such %" a little odd. Whether a fight remains in stand up, or on the ground, or in a car, or at your relatives bachelor party, it's still a fight. If someone doesn't have a good ground game, that's a weakness - if someone doesn't have good stand up that's a weakness, too. So, too, is lack of endurance, lack of will, lack of an offensive hammer and on and on. We all got weaker parts of our game. I guess that's why we still train.
