I can tell you that anything Sam is able to do on the football field is a miracle and his true disire to play football. I have the same thing as Sam. I was told by my doctor not to lift weights any more because of the strain on the heart. I spoke with someone that was a body builder & they stopped lifting after they found out about their bicupid. I have not needed to have my valve replaced yet. I am really amazed as to what Sam has been able to do so far after his surgery. My wife just had a heart transplant on Feb 22, so I know what heart surgery can do to a person. So I would say if Sam is just able to be out there and play that we should be very happy about that. If he can go out and regain that old 4* star ability, that would only add to the miracle. He's my hero already.
