It depends what you mean.
Are you assuming Lombardi rises from the grave today as the 57 year old man he was before he died, knowing nothing of the changing times and evolution of the game over the last 50 years? Rentering the game would be very difficult for obvious reasons, though the caricature of his personality as some harsh disciplinarian is a one-sided simplification. Demanding hard work, dedication and discipline never went out of style. He would probably appreciate how most players now treat conditioning as a year round job instead of having to burn off the fat in camp. In any case, nobody's going to hire a 57 year old intern to relearn everything, and the notoriety of being a man who rose from the dead intact after 48 years would keep him otherwise occupied.
Or are you assuming he was born 48 years later, was now 57 years old, and grew up in different times and in a different game? Would his approach have been the same? Surely not. Would he have invented the power sweep which was quite sophisticated with all kinds of variations based on the defensive alignments, an option run game. Unlikely. Would his football mind have invented something else? Perhaps. This scenario presents a different set of problems. He was a scholorship lineman at Fordam at 5' 8", 180 lbs. after being a fullback in high school not known for his athleticism. 50 years later he wouldn't have played college ball and might not have gotten off the bench in high school if he made the team at all. Without that experience he likely would never have gotten even a first job coaching, such as the high school assistant job he got through connections with his Fordham teammates.
No one is bound for success. It's a confluence of talent, place and time. That diminishes nothing, changes nothing.
