While Jeff is a more than adequate replacement, my concern is for Dale, Jr.. Are the concussion symptoms something from which he might fully recover? Will he ever be 100%? Dale, Jr., is an excellent spokesman and this is a great opportunity for him to tell others in all sports, about his injuries and press home the message on the danger of and ramifications of concussions resulting from sport related injuries.
Maybe Dale's symptoms will go away, and never recur, but my thoughts and best wishes are with Dale,Jr., even if he never returned to racing. He's been a gentleman throughout.
