I'd seriously consider getting your strength to 74, not 68.
Next time your role a G, 8's should be in throwing, catching, carrying, punting and kicking. Some would include jumping, but I'm open to that. That if you add it up is 5, plus the two in jumping. That could have seen your speed or agility higher.
Train agility/speed, or agility/vision depending on what type of guard your going to be.
