I wonder if Jack Nicklaus jumps off a bridge, Matt will as well...
Rob, that would not be a good way to determine whether or not architecture influences good player's to win since not all tournaments have the same caliber of field.
The simplest way to figure it out would be to take the best players from last 2 or 3 decades or so and gather all of their starts and wins to figure out their winning percentage (win/start) on top 20 courses, top 50 courses, top 100 courses, and the rest. It would be rough, but if there is a strong trend, this should show it.
There are a lot of things that great golfers believe that are completely false. It would not surprise me if this was one of them.
