Hogan's life and story is quite remarkable...really the father of the modern golf swing having penned perhaps the greatest golf book of all time and my personal favorite and the model I used coming up when learning the game. But who could play with that weak of a grip?
Hogan came up very hard and had a very stern demeanor. Word is his father commited suicide in his home which forever shaped young Hogan. If you have a chance to seek video of Hogan, its out there. I love the action of this swing including a pronounced lag/delayed hit that he got with a cupped left wrist which was the result of him fighting a hook from the early days including his restricted hip turn and famous stance. His swing seemed to perfectly repeat. My teacher was a disciple of Hogan and used his 5 lessons to teach me.
Although Nichlaus has perhaps the greatest golf record, many believe like you that Hogan was the best of all time. He was perhaps the most accurate ball striker but don't believe he could putt as well as Nichlaus or Woods...of course they putted on smoother greens.
Bobby Jones was a golfing prodigy and genius and Byron Nelson is in the mix as well including the late and great maestro Severiano Ballesteros who left us much too young.
