I would probably be going out on a limb here, but I would think overall that Ben Hogan is probably the best golfer I have heard of.
The reason I say that is when you look at how good his swing was, how well he did despite his best years being interrupted by World War II and then that horrible car wreck, I can't think of more challenging scenarios to overcome and still win like that. The one qualifier there would be putting. Hogan had legendary yips from what I understand.
As far as depth of competition getting better in today's world, I am not sure I buy that. If the average tour player today was really better than the average in Nicklaus's day, then you would I think see that reflected in the average score...and you don't. This is especially true given the fact everyone nowadays has so much better clubs and balls, not to mention launch monitors to fit them. Indeed, I would say all that stuff has maybe made the average joe better, but not the pros.
Give Tiger a off-the-shelf persimmon driver and one of those old golf balls, and put him up against Hogan in a game, it better come down to putting for Tiger's sake I think because ball striking and consistency I think Hogan would still own. Or change the scenario and give the Hawk a set of top o' dee line computer fitted TaylorMades and a box of Titleist Pro V1's and it would be the most amazing ball striking ever seen.
That said, Woods is easily the best today, and I think probably better than Nicklaus, he just wants it more.
