Nope, not Arnie. Not Jack either. Not even Tiger Woods.
That distinction belongs to the late great Bryson DeChambeau who this year had the entire golfing world believing that touch, knowledge, finesse, and even an appreciation for how difficult golf can be were all things of the past. He won some big tournaments and freely dispensed his superior knowledge of the game, based on sound engineering principles and the laws of physics.
What has he done to deserve this accolade, you ask? He entered this year's Masters as the favorite and in the first two rounds has basically dumped. Gone, at least for now, is all his self-congratulatory blather about the scientific approach which I think is terrible for the game.
FWIW, I also think that in various ways all three of the first named golfers did "save" the PGA tour. Arnie by being good and colorful--and great for TV. Jack by being a consistently great golfer. Tiger by being unbelievably good at an early age and at a time when the PGA tour needed him. He was a combination of Arnie and Jack and his own inimitable self. Oh, and he ain't white. I looked up the French meaning of DeChambeau, which basically means "from the fields." You know--the place were French farmers used to dump a lot of manure.
