Absolutely perfect footwork.   Look at his left heel free him up to make a huge huge huge turn.
Incredible footwork  !!  The best.

averaged 270 plus with balata balls and persimmon woods. he would have to get a flightplan with today's equipment.

Take that first swing and give today's driver / ball technology and the distance would be unbelievable.

after watching this video i reduced my score by 10 strokes.     I am now shooting in the 120's regularly!     I am so happy.

Just think what Jack would be like with this modern equipment

That first swing with modern technology would be INSANE! Gosh he was a heck of a player!

The pure athleticism of Jack's swing is astonishing. The all-over-body coordination, the "bigness" of his swing, the jaw-dropping lower body action that's so unbelievably controlled. Because Jack was a bit overweight coming out of Ohio State, and as he matured his body filled out, people have no idea just what a fantastic athlete the Golden Bear was. As a youngster Jack played baseball, football, basketball, and tennis, in addition to golf. He was good enough at basketball to be recruited to play at OSU. Nicklaus' father, Charlie, had played college football at OSU and then semi-pro football for the team that became the Detroit Lions. He also dominated area tennis, winning several city championships. Both men were exceptional all-around athletes with immense power and elite hand-eye coordination. To this day Jack insists that young people should be encouraged to play multiple sports, rather than concentrating solely on golf or any one activity. The only problem with that is most youngsters aren't blessed with world-class athleticism that makes excellence more realistic to attain.

Greatest of All Time!

Jack Nicklaus swing is like a Davinci painting...its beautiful and i could stare at it all dy every day

I have never seen a club accelerate through impact like that. You can't see that in full speed. It's crazy. It looks like the clubhead speed doubles through the impact zone.

If you take it back more vertical like Jack did, then when the right hip moves out during the start of the downswing, the club naturally lays off and the swing becomes flatter.  If you take it back more flat, then the start of the downswing makes the club naturally want to come over the top.

The most underrated gift ,which we all assume is only a little better with exceptional golfers, is hand-eye coordination.  To swing like Jack did at a young age and find the absolute center of the clubface, at a perfect angle-even with a stiff-impossible to hit pefect 1 - Iron; well he could do that probably dozens of times in a row before a slight mishit.  It's Lennon/McCartney in their prime...and it's not a recipe that can be copied, it's a gift.

LOOK AT THAT DRAMATIC PIVOT.!!!! That is the reason he won 18 majors !!!    Modern players must learn the huge pivot if they want to win big.

That’s how he won 20 majors

I love his swing - the rhythm and flow and harnessing of power.  I also think it's one of the most underrated swings  - coaches, commentators don't speak of it in the same breath of others, but to me it is remarkable, a work of art.

0:39 This is perfection. I cant imagine a more beautiful position at the top.

Ive been watching old masters final rounds the last few weeks, and was lucky enough to grow up there and go since ‘74. Funny part is i talked on the phone for an hour today with my best friend from college( we are 60 now) and ALL we talked about was how nicklaus,in retrospect, is even more amazing and impressive decades later than watching him then! Younger fans think LIV is great and they are ALL better athletes and better golfers, but Jack came along and decimated not only Arnold in his prime, but every great golfer for the next 25 years ALL in their primes, and collectively some of the very best golfers ever: palmer trevino player miller weiskopf kite crenshaw watson seve floyd norman……and the punchline is he won his last 4 or 5 NEVER playing his best, battling both putter and chipping, and still somehow persevering despite clearly past his prime…..

He shifted almost all his weight to his right foot.

Look at that momentum transfer at the moment of impact... Simply beautiful.
