After reading Beckman's statement, to me it sounds like John is still the same John in many ways but his condition as to whether he'll return to driving is 'guarded'. Sometimes you learn more from someone from what they didn't say than what they did say.
Remember when John had an emotional track-end interview several races back when he mentioned Prock was going to be his replacement? Like many others, I saw the writing on the wall right there and of course, he was physically fine at that time. Just my opinion, of course.
And you know what? Whatever the man, his family and his doctors decide is the right path for him, that'll be just fine and I believe everyone will give that opinion a big thumbs up. I realize there's been extensive talk and speculation on the subject but hey, it's John Force and a hell of a lot of people care deeply about the old boy.
