Yeah, I'd feel REAL comfortable with the docs telling me, we just repaired the hole in your heart, you can go play football. His heart will never, ever be ready to take the abuse playing football will cause. His heart is abnormal and will always be that way.
You hear of these athletes dropping dead during practice, or after a game in the locker room. The cause always seems to be heart related. He may be cleared, but I bet no doctor is telling him is advising him to rush out and try out his repaired heart.
He is not very bright if he tries to come back this year.
