I agree, but that doesn't put him up there with the greats of the game as some people are suggesting. He's young and he could go on to be the best player ever, but it's too early to say that imo.
It's really impossible to ever say who the greatest ever is/was. Certainly JS could be directly compared to Woods as their equipment, standard of courses etc. is the same. But how would guys like Young Tom Morris, Bobby Jones, Harry Vardon and Ben Hogan fare if we could bring them back now?
Imagine those 4 going head to head with Nicklaus, Palmer, Woods, Spieth? SKY would pay zillions for the TV rights of that!!
