Byron,
I respectfully disagree. Presentation is as much a part of fishing as pattern selection; his ability to put the fly where he wanted it, and at distances that a lot of us can still only dream about would allow him to get the fly to many fish in the river we couldn't touch. He probably wouldn't tuna-boat them fishing a #10 Wulff like in earlier times, especially water like The Ranch, but I think a person with his rare abilities would still do well by today's standards.
Regards,
Scott
