Tom,
Don't worry, I also don't think they are in the same league, but your comparrison makes for great discussion. I found it fun to say "what if they were and we (the golf world) just didn't get it?"
I have had the good fortune to see some of Picasso's early work and a series of interviews where he talked about his evolution as an artist. Picasso's place in art makes sense to me, but I wonder if all that perspective has helped. The canvas certainly was the right place for his expression
I have read articles about Muirhead, but I'll admit that I don't get what he's trying to do. Or may be as a golfer, I'm resistant to his ideas in the context of the game.
What I'm finding with this wonderful analogy is that he may possibly be the great maverick that Picasso was, but working in the wrong medium to gain any sort of acceptance.
Again back to Tabacco Road:
Stranz's Tobacco Road may be perceived as "out there" , 4 par 3's on the back of Pacific Dunes may be concidered outside the box, for me Bill Kittleman is "out there"; but in the anaolgy's context, they are not. All are quite conventional, drawing on variations of a common theme.
