	    I watched Luke Kuechly come off the field balling like an inconsolable child on his last or second last concussion. Retired due to concussions. 
	    Dan Morgan had 18 tackles and seven assists in the Super Bowl. His nickname on Charlotte local radio was Douthful Dan because of his injury status. Retired early for concussions.  
	    Tua needs to hang it up. Ego and love of football might cause him to choose otherwise but as others have said, he is simply physically incapable of being a QB in the NFL.
